So, none of these apply? This could be because of one of the following reasons: Another administrator is currently moving the mailbox. The mailbox is locked. The Microsoft Exchange Mailbox Replication service (MRS) doesn't have the correct permissions. Network errors are preventing MRS from cleanly closing its session with the Mailbox server. If this is the case, MRS may continue to encounter this error for up to 2 hours - this duration is controlled by the TCP KeepAlive settings on the Mailbox server. Wait for the mailbox to be released before attempting to move this mailbox again.

Yes, you are right. One of my colleague attempted to move the same mailbox but the move failed and he disconnected the RDP session from the Mailbox Server so i believe this was hanging the new request however i forced to log off my colleague's session and then tried. It is fine now the MBX is in moving progress. Thanks, MaqsoodMaqsood Mohammed Senior Systems Engineer MCITP-Enterprise Admin & ITILv3 Foundation Certified
