You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Message configuration" entry in the Recipients Permissions topic.


Parameter Required Type Description




The Identity parameter identifies the mailbox. You can use one of the following values:

  • GUID

  • Distinguished name (DN)

  • Domain\Account

  • User principal name (UPN)

  • LegacyExchangeDN

  • SmtpAddress

  • Alias




This parameter is available only in on-premises Exchange 2016.

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.




If the VerifyDefaultFolderNameLanguage parameter is set to $true, the DefaultFolderNameMatchingUserLanguage property returned by the task indicates whether the mailbox default folder names are localized with the language specified for the mailbox. If this parameter isn't specified, the property isn't returned by the task. This parameter can only be used by the mailbox owner. If a non-mailbox owner tries to run the command on the mailbox with this parameter, an error is reported. The default value is $false.
