I'm on one of my last steps in migrating from 2010 to 2013. When I issue the command to Resume the migration request after the Autosuspend happens, I get a StalledDueToMailBoxLock, and it retries but never completes. I've removed the request and tried it again, but I get the same thing. The requests were 24 hours apart. I have no clients that are connecting to the 2010 server anymore, and all the user mailboxes have been migrated to 2013 successfully. I haven't found much online about this status, so I'm at a loss. By the way, this is during my Public Folder migration process. Sorry for leaving that out.
Thank you.
