<MultiValuedProperty>] [-WhatIf] [-WindowsEmailAddress <SmtpAddress>] [<CommonParameters>] DESCRIPTION You can use this cmdlet for one mailbox at a time. To perform bulk management, you can pipeline the output of various Get- cmdlets (for example, the Get-Mailbox or Get-User cmdlets) and configure several mailboxes in a single-line command. You can also use the Set-Mailbox cmdlet in scripts. You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet. EXAMPLES EXAMPLE 1 PowerShell Copy Set-Mailbox -Identity "John Woods" -DeliverToMailboxAndForward $true -ForwardingSMTPAddress manuel@contoso.com This example delivers John Woods's email messages to John's mailbox and also forwards them to Manuel Oliveira's (manuel@contoso.com) mailbox. EXAMPLE 2 PowerShell Copy Get-Mailbox -OrganizationalUnit "Marketing" | Set-Mailbox -UseDatabaseQuotaDefaults $false -IssueWarningQuota 200MB -ProhibitSendQuota 250MB -ProhibitSendReceiveQuota 280MB This example uses the Get-Mailbox cmdlet to find all the mailboxes in the Marketing organizational unit, and then uses the Set-Mailbox cmdlet to configure these mailboxes. The custom warning, prohibit send, and prohibit send and receive limits are set to 200 megabytes (MB), 250 MB, and 280 MB respectively, and the mailbox database's default limits are ignored. EXAMPLE 3 PowerShell Copy Get-User -Filter "Department -eq 'Customer Service'" | Set-Mailbox -MaxSendSize 2MB This example uses the Get-User command to find all users in the Customer Service department, and then uses the Set-Mailbox command to change the maximum message size for sending messages to 2 MB. EXAMPLE 4 PowerShell Copy Set-Mailbox John@contoso.com -MailTipTranslations ("FR: C'est la langue française", "CHT: 這是漢語語言") This example sets the MailTip translation in French and Chinese. EXAMPLE 5 PowerShell Copy $password = Read-Host "Enter password" -AsSecureString Set-Mailbox florencef -Password $password -ResetPasswordOnNextLogon $true In on-premises Exchange, this example resets the password for Florence Flipo's mailbox. The next time she signs in to her mailbox, she'll have to change her password. EXAMPLE 6 PowerShell Copy Set-Mailbox -Arbitration -Identity "SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c}" -MessageTracking $false Set-Mailbox -Arbitration -Identity "SystemMailbox{1f05a927-b864-48a7-984d-95b1adfbfe2d}" -MessageTracking $true This example removes the message tracking organization capability from the arbitration mailbox named SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c} and assigns it to an arbitration mailbox named SystemMailbox{1f05a927-b864-48a7-984d-95b1adfbfe2d}. EXAMPLE 7 PowerShell Copy Set-Mailbox -Identity "John Woods" -EmailAddresses @{add="Jwoods@contoso.com"} This example adds a secondary email address to John's mailbox. EXAMPLE 8 PowerShell Copy Set-Mailbox -Identity asraf@contoso.com -RemoveDelayReleaseHoldApplied In Exchange Online, this example removes the delay hold that's applied to Asraf's mailbox so an offboarding migration (that is, a mailbox migration from Exchange Online back to on-premises Exchange) can continue successfully. For more information about delay holds, see Managing mailboxes on delay hold. PARAMETERS -ACCEPTMESSAGESONLYFROM The AcceptMessagesOnlyFrom parameter specifies who is allowed to send messages to this recipient. Messages from other senders are rejected. Valid values for this parameter are individual senders in your organization (mailboxes, mail users, and mail contacts). You can use any value that uniquely identifies the sender. For example: * Name * Alias * Distinguished name (DN) * Canonical DN * Email address * GUID You can enter multiple senders separated by commas. To overwrite any existing entries, use the following syntax: Sender1,Sender2,...SenderN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Sender1","Sender2",..."SenderN". To add or remove senders without affecting other existing entries, use the following syntax: @{Add="Sender1","Sender2"...; Remove="Sender3","Sender4"...}. The senders you specify for this parameter are automatically copied to the AcceptMessagesOnlyFromSendersOrMembers property. Therefore, you can't use the AcceptMessagesOnlyFrom and AcceptMessagesOnlyFromSendersOrMembers parameters in the same command. By default, this parameter is blank ($null), which allows this recipient to accept messages from all senders. Expand table Type:MultiValuedProperty Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online -ACCEPTMESSAGESONLYFROMDLMEMBERS The AcceptMessagesOnlyFromDLMembers parameter specifies who is allowed to send messages to this recipient. Messages from other senders are rejected. Valid values for this parameter are groups in your organization (distribution groups, mail-enabled security groups, and dynamic distribution groups). Specifying a group means all members of the group are allowed to send messages to this recipient. You can use any value that uniquely identifies the group. For example: * Name * Alias * Distinguished name (DN) * Canonical DN * Email address * GUID You can enter multiple groups separated by commas. To overwrite any existing entries, use the following syntax: Group1,Group2,...GroupN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Group1","Group2",..."GroupN". To add or remove groups without affecting other existing entries, use the following syntax: @{Add="Group1","Group2"...; Remove="Group3","Group4"...}. The groups you specify for this parameter are automatically copied to the AcceptMessagesOnlyFromSendersOrMembers property. Therefore, you can't use the AcceptMessagesOnlyFromDLMembers and AcceptMessagesOnlyFromSendersOrMembers parameters in the same command. By default, this parameter is blank ($null), which allows this recipient to accept messages from all groups. Expand table Type:MultiValuedProperty Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online -ACCEPTMESSAGESONLYFROMSENDERSORMEMBERS The AcceptMessagesOnlyFromSendersOrMembers parameter specifies who is allowed to send messages to this recipient. Messages from other senders are rejected. Valid values for this parameter are individual senders and groups in your organization. Individual senders are mailboxes, mail users, and mail contacts. Groups are distribution groups, mail-enabled security groups, and dynamic distribution groups. Specifying a group means all members of the group are allowed to send messages to this recipient. To specify senders for this parameter, you can use any value that uniquely identifies the sender. For example: * Name * Alias * Distinguished name (DN) * Canonical DN * Email address * GUID You can enter multiple senders separated by commas. To overwrite any existing entries, use the following syntax: Sender1,Sender2,...SenderN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Sender1","Sender2",..."SenderN". To add or remove individual senders or groups without affecting other existing entries, use the AcceptMessagesOnlyFrom and AcceptMessageOnlyFromDLMembers parameters. The individual senders and groups you specify for this parameter are automatically copied to the AcceptMessagesOnlyFrom and AcceptMessagesOnlyFromDLMembers properties, respectively. Therefore, you can't use the AcceptMessagesOnlyFromSendersOrMembers parameter and the AcceptMessagesOnlyFrom or AcceptMessagesOnlyFromDLMembers parameters in the same command. By default, this parameter is blank ($null), which allows this recipient to accept messages from all senders. Expand table Type:MultiValuedProperty Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online -ACCOUNTDISABLED This parameter is functional only in the cloud-based service. The AccountDisabled parameter specifies whether to disable the account that's associated with the mailbox. Valid values are: * $true: The associated account is disabled. The user can't log in to the mailbox. * $false: The associated account is enabled. The user can log in to the mailbox. Expand table Type:Boolean Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection -ADDRESSBOOKPOLICY The AddressBookPolicy parameter specifies the address book policy that's applied to the mailbox. You can use any value that uniquely identifies the address book policy. For example: * Name * Distinguished name (DN) * GUID For more information about address book policies, see Address book policies in Exchange Server or Address book policies in Exchange Online. Expand table Type:AddressBookMailboxPolicyIdParameter Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online -ALIAS The Alias parameter specifies the Exchange alias (also known as the mail nickname) for the recipient. This value identifies the recipient as a mail-enabled object, and shouldn't be confused with multiple email addresses for the same recipient (also known as proxy addresses). A recipient can have only one Alias value. The maximum length is 64 characters. The Alias value can contain letters, numbers and the following characters: * !, #, %, *, +, -, /, =, ?, ^, _, and ~. * $, &, ', `, {, }, and | need to be escaped (for example -Alias what`'snew) or the entire value enclosed in single quotation marks (for example, -Alias 'what'snew'). The & character is not supported in the Alias value for Microsoft Entra Connect synchronization. * Periods (.) must be surrounded by other valid characters (for example, help.desk). * Unicode characters U+00A1 to U+00FF. When you create a recipient without specifying an email address, the Alias value you specify is used to generate the primary email address (alias@domain). Supported Unicode characters are mapped to best-fit US-ASCII text characters. For example, U+00F6 (ö) is changed to oe in the primary email address. If you don't use the Alias parameter when you create a recipient, the value of a different required parameter is used for the Alias property value: * Recipients with user accounts (for example, user mailboxes, and mail users): The left side of the MicrosoftOnlineServicesID or UserPrincipalName parameter is used. For example, helpdesk@contoso.onmicrosoft.com results in the Alias property value helpdesk. * Recipients without user accounts (for example, room mailboxes, mail contacts, and distribution groups): The value of the Name parameter is used. Spaces are removed and unsupported characters are converted to question marks (?). If you modify the Alias value of an existing recipient, the primary email address is automatically updated only in environments where the recipient is subject to email address policies (the EmailAddressPolicyEnabled property is True for the recipient). The Alias parameter never generates or updates the primary email address of a mail contact or a mail user. Expand table Type:String Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online -ANTISPAMBYPASSENABLED This parameter is available only in on-premises Exchange. The AntispamBypassEnabled parameter specifies whether to skip anti-spam processing on the mailbox. Valid values are: * $true: Anti-spam processing is skipped on the mailbox. * $false: Anti-spam processing occurs on the mailbox. This is the default value Expand table Type:Boolean Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 -APPLYMANDATORYPROPERTIES The ApplyMandatoryProperties switch specifies whether to update the msExchVersion attribute of the mailbox. You don't need to specify a value with this switch. You might need to use this switch to fix inaccessible mailboxes or mailboxes that were created in previous versions of Exchange. Expand table Type:SwitchParameter Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online -ARBITRATION This parameter is available only in on-premises Exchange. The Arbitration switch is required to modify arbitration mailboxes. You don't need to specify a value with this switch. Arbitration mailboxes are system mailbox that are used for storing different types of system data and for managing messaging approval workflow. To modify arbitration mailboxes that are used to store audit log settings or data, don't use this switch. Instead, use the AuditLog or AuxAuditLog switches. Expand table Type:SwitchParameter Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 -ARBITRATIONMAILBOX This parameter is available only in on-premises Exchange. The ArbitrationMailbox parameter specifies the arbitration mailbox that's used to manage the moderation process for this recipient. You can use any value that uniquely identifies the arbitration mailbox. For example: * Name * Alias * Distinguished name (DN) * Canonical DN * Domain\Username * Email address * GUID * LegacyExchangeDN * SamAccountName * User ID or user principal name (UPN) Expand table Type:MailboxIdParameter Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 -ARCHIVEDATABASE This parameter is available only in on-premises Exchange. The ArchiveDatabase parameter specifies the Exchange database that contains the archive that's associated with this mailbox. You can use any value that uniquely identifies the database. For example: * Name * Distinguished name (DN) * GUID Expand table Type:DatabaseIdParameter Position:Named Default value:None Required:False Accept pipeline input:False Accept wildcard characters:False Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 -ARCHIVEDOMAIN This parameter is available only in on-premises Exchange.

In on-premises Exchange organizations, the primary SMTP address and other proxy addresses are typically set by email address policies. However, you can use this parameter to configure other proxy addresses for the recipient. For more information, see Email address policies in Exchange Server. Valid syntax for this parameter is "Type:EmailAddress1","Type:EmailAddress2",..."Type:EmailAddressN". The optional Type value specifies the type of email address. Examples of valid values include: * SMTP: The primary SMTP address. You can use this value only once in a command. * smtp: Other SMTP email addresses. * X400: X.400 addresses in on-premises Exchange. * X500: X.500 addresses in on-premises Exchange. If you don't include a Type value for an email address, the address is assumed to be an SMTP email address. The syntax of SMTP email addresses is validated, but the syntax of other email address types isn't validated. Therefore, you need to verify that any custom addresses are formatted correctly. To specify the primary SMTP email address, you can use any of the following methods: * Use the Type value SMTP on the address. * The first email address when you don't use any Type values, or when you use multiple lowercase smtp Type values. * Use the PrimarySmtpAddress parameter instead. You can't use the EmailAddresses parameter and the PrimarySmtpAddress parameter in the same command. The PrimarySmtpAddress parameter updates the primary email address and WindowsEmailAddress property to the same value. To replace all existing proxy email addresses with the values you specify, use the following syntax: "Type:EmailAddress1","Type:EmailAddress2",..."Type:EmailAddressN". To add or remove specify proxy addresses without affecting other existing values, use the following syntax: @{Add="Type:EmailAddress1","Type:EmailAddress2",...; Remove="Type:EmailAddress3","Type:EmailAddress4",...}.

The EnableRoomMailboxAccount parameter specifies whether to enable the disabled user account that's associated with this room mailbox. Valid values are: * $true: The disabled account that's associated with the room mailbox is enabled. You also need to use the RoomMailboxPassword with this value. The account is able to log in and access the room mailbox or other resources. * $false: The account that's associated with the room mailbox is disabled. The account is not able to log in and access the room mailbox or other resources. In on-premises Exchange, this is the default value. You need to enable the account for features like the Skype for Business Room System or Microsoft Teams Rooms. A room mailbox in Exchange Online is created with associated an account that has a random, unknown password. This account is active and visible in Microsoft Graph PowerShell and the Microsoft 365 admin center just like a regular user account, but it consumes no licenses. To prevent this account from being able to log in after you create the mailbox, use the AccountEnabled parameter on the Update-MgUser cmdlet in Microsoft Graph PowerShell.

The ImListMigrationCompleted parameter specifies whether a user's Lync or Skype for Business contact list is stored in their mailbox. Valid values are: * $true: The user's Lync or Skype for Business contact list is stored in their Exchange 2016 mailbox. This prevents you from migrating the mailbox back to an Exchange 2010 server. * $false: The user's Lync or Skype for Business contact list is stored on a Lync or Skype for Business server. This doesn't prevent you from migrating the mailbox back to an Exchange 2010 server. This is the default value. Lync Server 2013 and Skype for Business Server 2015 support storing the user's contact list in their Exchange 2016 mailbox. This feature is known as the unified contact store (UCS), and it allows applications to show a consistent, up-to-date contact list. However, Exchange 2010 doesn't support the unified contact store. Therefore, before you migrate a user's Exchange 2016 mailbox back to Exchange 2010, you need to move the user's Lync or Skype for Business contact list from the unified contact store back to a Lync 2013 or Skype for Business server. For more information, see Configuring Microsoft Lync Server 2013 to use the unified contact store. If you migrate an Exchange 2013 mailbox back to Exchange 2010 while the user's Lync or Skype for Business contact list is stored in the unified contact store, the user could permanently lose access to those contacts. After you verify the user's Lync or Skype for Business contact list has been moved back to a Lync 2013 or Skype for Business server, you should be able to complete the mailbox migration. If you need to migrate the mailbox despite the potential for data loss, you can manually set the ImListMigrationCompleted parameter to $false.

If federation is configured for this mailbox and you don't set this parameter when you create the mailbox, Exchange creates the value for the immutable ID based upon the mailbox's ExchangeGUID and the federated account namespace, for example, 7a78e7c8-620e-4d85-99d3-c90d90f29699@mail.contoso.com. You need to set the ImmutableId parameter if Active Directory Federation Services (AD FS) is deployed to allow single sign-on into an off-premises mailbox and AD FS is configured to use a different attribute than ExchangeGUID for sign-on token requests. Both, Exchange and AD FS must request the same token for the same user to ensure proper functionality for a cross-premises Exchange deployment scenario.

The InactiveMailbox switch specifies that the mailbox is an inactive mailbox. You don't need to specify a value with this switch. An inactive mailbox is a mailbox that's placed on Litigation Hold or In-Place Hold before it's soft-deleted. To find inactive mailboxes, run the command Get-Mailbox -InactiveMailboxOnly | Format-List Name,PrimarySmtpAddress,DistinguishedName,ExchangeGuid and then use the DistinguishedName or ExchangeGuid property values for the Identity parameter (values guaranteed to be unique). This switch is required to use the LitigationHoldEnabled and LitigationHoldDuration parameters on inactive mailboxes. You can't use this switch to modify other properties on inactive mailboxes.

For load-balancing purposes, users are equally distributed across public folder mailboxes by default. When this parameter is set on a public folder mailbox, that mailbox isn't included in this automatic load-balancing and won't be accessed by users to retrieve the public folder hierarchy. However, if an administrator has set the DefaultPublicFolderMailbox property on a user mailbox to a specific public folder mailbox, the user will still access the specified public folder mailbox even if the IsExcludedFromServingHierarchy parameter is set for that public folder mailbox.

If the mailbox reaches or exceeds this size, the user receives a descriptive warning message. A valid value is a number up to 1.999999999 terabytes (2199023254528 bytes) or the value unlimited. When you enter a number, you can qualify it with one of the following units: * B (bytes) * KB (kilobytes) * MB (megabytes) * GB (gigabytes) * TB (terabytes) Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte. The IssueWarningQuota value must be less than or equal to the ProhibitSendReceiveQuota value. In Exchange Online, the quota value is determined by the subscriptions and licenses that administrators purchase and assign in the Microsoft 365 admin center. You can lower the quota value, and you may be able to raise the quota, but you can't exceed the maximum value that's allowed by the subscription or license. In Exchange Online, you can't use this parameter on public folder mailboxes. In on-premises Exchange, the default value of this parameter is unlimited. When the UseDatabaseQuotaDefaults parameter on the mailbox is set to $true (the default value), the value of the this parameter is ignored, and the mailbox uses the IssueWarningQuota value from the mailbox database.

A valid value is a number up to 1.999999999 terabytes (2199023254528 bytes) or the value unlimited. When you enter a number, you can qualify it with one of the following units: * B (bytes) * KB (kilobytes) * MB (megabytes) * GB (gigabytes) * TB (terabytes) Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte. The ProhibitSendQuota value must be less than or equal to the ProhibitSendReceiveQuota value. In Exchange Online, the quota value is determined by the subscriptions and licenses that administrators purchase and assign in the Microsoft 365 admin center. You can lower the quota value, and you may be able to raise the quota, but you can't exceed the maximum value that's allowed by the subscription or license. In Exchange Online, you can't use this parameter on public folder mailboxes. In on-premises Exchange, the default value of this parameter is unlimited. When the UseDatabaseQuotaDefaults parameter on the mailbox is set to the value $true (the default value), the value of the this parameter is ignored, and the mailbox uses the ProhibitSendQuota value from the mailbox database. To use this parameter to enforce a specific quota value for the mailbox, you need to set the UseDatabaseQuotaDefaults parameter to the value $false.

The RemoveOrphanedHolds parameter is used to remove the mailbox (typically, an inactive mailbox) from In-Place Holds that no longer exist, but are still applied to the mailbox. You identify the In-Place Hold by using its GUID value. You can specify multiple GUID values separated by commas. If you use the GUID value of an In-Place Hold that still exists as a value for this parameter, the command will return an error. If that happens, you'll need to remove the mailbox (or inactive mailbox) from the In-Place Hold. In an Exchange hybrid deployment, In-Place Holds that are created in the on-premises organization can be applied to cloud-based mailboxes. In this scenario, it's possible that the hold object hasn't been synced to the cloud-based organization, and using this parameter will remove the specified hold from the cloud-based mailbox even though the hold may still exist. To prevent this from happening, make sure the hold doesn't exist in the on-premises organization before you use this parameter.

Soft-deleted items are items that have been deleted by using any of these methods: * Deleting items from the Deleted Items folder. * Selecting the Empty Deleted Items Folder action. * Deleting items using Shift + Delete. These actions move the items into the Recoverable Items\Deletions folder. Before the deleted item retention period expires, users can recover soft-deleted items in Outlook and Outlook on the web by using the Recover Deleted Items feature. For more information, see Recoverable Items folder in Exchange Server. To specify a value, enter it as a time span: dd.hh:mm:ss where dd = days, hh = hours, mm = minutes, and ss = seconds. The default value is 14 days (14.00:00:00). In Exchange Online, you can increase the value to a maximum of 30 days. In Exchange Online, you use this parameter to configure the deleted item retention on existing mailboxes. Use the Set-MailboxPlan cmdlet to change the RetainDeletedItemsFor value for all new mailboxes that you create in the future. In on-premises Exchange, when the UseDatabaseQuotaDefaults parameter on the mailbox is set to the value $true (the default value), the value of the this parameter is ignored, and the mailbox uses the DeletedItemRetention value from the mailbox database.

The UMDtmfMap parameter specifies the dual-tone multiple-frequency (DTMF) map values for the recipient. This allows the recipient to be identified by using a telephone keypad in Unified Messaging (UM) environments. Typically, these DTMF values are automatically created and updated, but you can use this parameter to make changes manually. This parameter uses the following syntax: * emailAddress:<integers> * lastNameFirstName:<integers> * firstNameLastName:<integers> To enter values that overwrite all existing entries, use the following syntax: emailAddress:<integers>,lastNameFirstName:<integers>,firstNameLastName:<integers>. If you use this syntax and you omit any of the DTMF map values, those values are removed from the recipient. For example, if you specify only emailAddress:<integers>, all existing lastNameFirstName and firstNameLastName values are removed. To add or remove values without affecting other existing entries, use the following syntax: @{Add="emailAddress:<integers>","lastNameFirstName:<integers>","firstNameLastName:<integers>"; Remove="emailAddress:<integers>","lastNameFirstName:<integers>","firstNameLastName:<integers>"}. If you use this syntax, you don't need to specify all of the DTMF map values, and you can specify multiple DTMF map values. For example, you can use @{Add="emailAddress:<integers1>","emailAddress:<integers2>} to add two new values for emailAddress without affecting the existing lastNameFirstName and firstNameLastName values.
