Description

The New-RemoteMailbox cmdlet creates an on-premises mail user. The mail user contains a specific attribute, which indicates that an associated mailbox in the service should be created when the user is synchronized to the service using directory synchronization.

Directory synchronization must be configured correctly for a mailbox to be created in the service. Creation of the mailbox in the service isn't immediate and depends on the directory synchronization schedule.

The policies that you apply to recipients in the on-premises Exchange organization, such as Unified Messaging or compliance policies, aren't applied to mailboxes in the service. You must configure policies in the service if you want policies to be applied to recipients in the service.

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

$Credentials = Get-Credential

New-RemoteMailbox -Name "Kim Akers" -Password $Credentials.Password -UserPrincipalName kim@corp.contoso.com

This example creates an on-premises mail user and its associated mailbox in the service. The remote routing address doesn't need to be specified because mail flow between the on-premises organization and the service has been configured. Using this configuration, the New-RemoteMailbox cmdlet automatically calculates the SMTP address of the mailbox to be used with the RemoteRoutingAddress parameter. This example also assumes directory synchronization has been configured.

The first command stores the password to use with the new remote mailbox in a variable by using the Get-Credential cmdlet. The last command creates the mail user.

After the new mail user is created, directory synchronization synchronizes the new mail user to the service and the associated mailbox is created.

Example 2

$Credentials = Get-Credential

New-RemoteMailbox -Name "Kim Akers" -Password $Credentials.Password -UserPrincipalName kim@corp.contoso.com -OnPremisesOrganizationalUnit "corp.contoso.com/Archive Users" -Archive

This example does the following steps:

Creates an on-premises mail user. The mail user is placed in the contoso.com/Archive Users OU. The OU has no effect on the mailbox in the service.

Creates the associated mailbox in the service.

Creates an archive mailbox in the service for the mailbox.

As in Example 1, this example assumes that mail flow and directory synchronization have been properly configured.

Parameters

-AccountDisabled

The AccountDisabled switch specifies whether to create the mail user in a disabled state. You don't need to specify a value with this switch.

Type:SwitchParameter
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ACLableSyncedObjectEnabled

The ACLableSyncedObjectEnabled switch specifies whether the remote mailbox is an ACLableSyncedMailboxUser. You don't need to specify a value with this switch.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-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.

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

-Archive

The Archive switch specifies whether to also create an archive mailbox in the service. You don't need to specify a value with this switch.

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

-Confirm

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
Type:SwitchParameter
Aliases:cf
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

-DisplayName

The DisplayName parameter specifies the display name of the mail user and the associated mailbox in the service. The display name is visible in the Exchange admin center, in address lists, and in Outlook. The maximum length is 256 characters. If the value contains spaces, enclose the value in quotation marks (").

If you don't use the DisplayName parameter, the value of the Name parameter is used for the display name.

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

-DomainController

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

Type:Fqdn
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

-Equipment

The Equipment switch specifies that the mailbox in the service should be created as an equipment resource mailbox. You don't need to specify a value with this switch.

Equipment mailboxes are resource mailboxes that aren't associated with a specific location (for example, vehicles or computers).

You can't use this switch with the Room switch.

Type:SwitchParameter
Position:Named
Default value:None
Required:True
Accept pipeline input:False

Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ImmutableId

The ImmutableId parameter is used by GAL synchronization (GALSync) and specifies a unique and immutable identifier in the form of an SMTP address for an Exchange mailbox used for federated delegation when requesting Security Assertion Markup Language (SAML) tokens. 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.

  • Name
  • Alias
  • Distinguished name (DN)
  • Canonical DN
  • Email address
  • GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".
