This is setting up a new Exchange Server 2013 to join with one existing Exch2k13 server. The objective is, moving all of the mailboxes from old server to this new server. However, I tried from ECP, and the status shown completed, but none was synced and moved.
I tried with powershell command - new-moverequest, and found that some mailboxes can moved but only one, with total size of 16.0 gb. When I tried on this failed mailbox again, it shows inprogress, but 2 hours later, it shows failed.
Why the move failed? How should I troubleshoot and get the mailbox migrated successfully?
