stuck importing mailbox
When I opened mail, it started importing mailboxes and seems to be stuck without error message saying " imported 69277 of 250066 messages".
This happened when I opened mail after a change of hard disk on my MBP. I had just recovered using a Time Machine backup.
Does anybody know how to solve this problem or how to determine the location of the message that's creating the problem?
MacBook Pro, OS X Mountain Lion (10.8.5), Mail application
