Sounds like the mailbox is being quarantined. You may need to repair the mailbox. Here is where and how you can check:

From: [email protected] [mailto:[email protected]] On Behalf Of Stringham, Steven Sent: Tuesday, January 7, 2014 4:07 PM To: [email protected] Subject: [Exchange] Mailbox locking up... Environment - Ex2010 SP2 RU6. From time to time (once/twice a week) we have a mailbox (this is a moving target โ not the same one) that decides to refuse all connection attempts. Everyone else in that database (and others) are able to connect to their mailbox. But, whichever is the lucky one at that moment will not be viewed. Not with OWA, the Outlook client, active sync, nothing. I check the current connections via get-logonstaticstics and the count is not that high, and I have increased the rpc policies, so that should not be it. I have found nothing that lets me get that client back online, other than just waiting. Sometimes 10 minutes, sometimes up to 2 hours. If I just sit on my hands, sooner or later the mailbox becomes available again. It is in a DAG situation, so I have migrated the active database (to kill any active connections) from one server to the other. This still does not free up the mailbox. I am wondering if there is a possibility that the mailbox got corrupted (these are very large mailboxes โ 10g to 90g) and the database is locking the mailbox and doing some kind of a repair. If this is the case, I have not found anything in the event logs that indicate this. Any thoughts? Anybody else run into something like this?
