Consider the following scenario:

  • You have Cumulative Update 5 or Cumulative Update 6 for Microsoft Exchange Server 2013 installed in your environment.

  • The IsExcludedFromProvisioning parameter is set to true in the environment.

  • You try to move a mailbox to a mailbox database.

In this scenario, the process fails, and you receive the following error message:

New-MoveRequest Mailboxname -TargetDatabase Databasename
The database Database is excluded from provisioning. Please select a different target database for the move.
+ CategoryInfo : InvalidArgument: (mailbox:MailboxOrMailUserIdParameter)
[New-MoveRequest], DatabaseExclude...ioningException
[FailureCategory=Cmdlet-DatabaseExcludedFromProvisioningException] 124EB7A0


  • This issue only occurs in Cumulative Update 5 or Cumulative Update 6.

  • Setting IsExcludedFromProvisioning to true excludes a specific mailbox database from an automatic mailbox distribution operation to store new or moved mailboxes when a mailbox database is not explicitly specified. When an administrator moves a mailbox and specifies the mailbox database, the Move Request service skips checking this feature and allows for sending successful move requests.


This issue occurs because the Move Request service does not skip checking the IsExcludedFromProvisioning flag for an administrator who sends the move requests in Cumulative Update 5 or Cumulative Update 6.


To resolve this issue, install Cumulative Update 7 for Exchange Server 2013.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
