Hi,
This is frustrating the hell out of me I have been working on this for three weeks now.
I have 3 Exchange 2013 Mailbox Database Servers that are part of a DAG. I am migrating Mailboxes from Exchange 2010 that are in a coexist at the moment. I have migrated about 75% of the mailboxes already but these last 3 weeks I havent been able to migrate anything.
I have rebooted all of the Exchange servers, all of the Dags are healthy, all the conent index'es are healthy, everything is always online, no issues whatsoever.
When I try to migrate a mailbox it sits at Syncing forever and never moves. The contentsumbitters isnt the issue since I have migrated mailboxes before. I have checked some of the migration logs it doesnt report anything.
I have used all the powershell commands to look the migration it just shows queued in the status, nothing else is in front.
Any assistance on this one would be greatly appreciated. I might have to open a ticket with MS.
