I just spent two entire days creating subfolders within my InBox and manually moving all of my Entourage 2007 mail into Outlook 2010.
Since they take a while to move, I have been doing it about 100 mails at a time and leaving the computer to do other things. I just came back and there was some kind of server error (sorry. I don't remember the exact text). I tried moving additional mail and nothing would move. So I rebooted.
Opened up Outlook and every single one of the subfolders I have created in the last 48 hours is missing, as are the thousands of mails I moved.
Looks like they don't have a smiley for Crying.

Anyone have ideas where the mail might be? I just can't do this again. It's taken me 6-7 weeks to get everything else from my Mac configured and moved over. This was supposed to be the last of it.
