I had opened another thread where in I had e-mail accounts two using IMAP and one using exchange 2010. For some strange reason around 12/21/11 all of my inboxes disappeared without a trace. That day mail was being sluggish activiity monitor was busy but I did not realiize realize what it was doing until too late. None of my messages showed up in the trash or deleted messages folder, they all just went straight into a black hole. With the two IMAP mailboxes I was able to do a time machine restore of a backup done on 12/20. These mailboxes only contained a few thousand so it was relatively quick an hour or so each. After the restore I moved the messages from the local recovered folder to the inbox all is happy. When I tried doing the exchange inbox with 30684 it would hang on the restore. I would select the inbox then launch time machine. I would go to the date 12/20/11, the inbox would start a count of the inbox contents ultimately ending up with 30684 messages. I would then do a cmd-a and it would select all 30684 messages and in about 2+ hours the daisy wheel is done selecting and a message would pop up on the lower pane and say something like "click on the restore button to recover 30684 messages." I would then click on the restore button and leave it. I've left it as long as a week and it was just stuck there and I had to force quit mail. I tried that process again and would leave it over night the next morning it would still be stuck at that last screen when I clicked recover but the time machine disk has stopped popping the popcorn. It would be totally stock and only thing I could do was force quit mail. Clicking on cancel or anything else would not respond.
Please help restore 30684 messages tell me about a finding a work around. I can browse backups so there has to be a way to get them back...
one example is this
/Volumes/Time Machine Backups/Backups.backupdb/mpitogo-mbp/2011-12-20-113717/Macintosh HD/Users/mpitogo/Library/Mail/V2/EWSemail@example.com/Inbox.mbox/71BA922B-5E27-4F12-93EE-21CC8DBFEF27/Data/0/0/1/Messages
