Use the Remove-MailUser cmdlet to remove an existing mail-enabled user from the Active Directory directory service.

Remove-MailUser -Identity <MailUserIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-IgnoreDefaultScope <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

The Remove-MailUser cmdlet removes an existing mail-enabled user object from the Active Directory directory service.

To run the Remove-MailUser cmdlet, the account you use must be delegated the following:

  • Exchange Recipient Administrator role

  • Account Operator role for the applicable Active Directory containers

For more information about permissions, delegating roles, and the rights that are required to administer Microsoft Exchange Server 2007, see Permission Considerations.


Parameter Required Type Description




This parameter specifies the identity of the mail user.




The Confirm parameter causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm parameter.




To specify the fully qualified domain name of the domain controller that writes this configuration change to Active Directory, include the DomainController parameter on the command.




The IgnoreDefaultScope parameter instructs the command to ignore the default recipient scope setting for the Exchange Management Shell and use the entire forest as the scope. This allows the command to access Active Directory objects that are not currently in the default scope. Using the IgnoreDefaultScope parameter introduces the following restrictions:

  • You cannot use the DomainController parameter. The command will use an appropriate global catalog server automatically.

  • You can only use the DN for the Identity parameter. Other forms of identification, such as alias or GUID, are not accepted.




The WhatIf parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf parameter.


Error Description



Exceptions Description


In this example, the Remove-MailUser command is used to remove the mail-enabled user Ted Bremer from Active Directory.
