I have a couple of people whos mailboxes refuse to migrate from exchange 2003 to exchange 2010. The other 300 users moved with no issues but getting a "unable to modify table" on 2 people and it fails ...

Doing some major cleanup on mailboxes in the company and finding a lot of mailboxes with 100k-800k items in their Deleted Items, Inbox, or other folders. What is the best way to bulk delete this stuff ...
