Sorry for bringing up so old post, but i ran with same problem: migration wizard cant copy mail from exchange with same warnings.
Code:
**Warning**: 6 Table Rows Requested, Got just 0, hr = 0
I checked event log on exchange server and found no events 9646. Anyways, i've done all steps, that were described in KB article from few posts above, but still no luck.
The problem is, that failed mailboxes belongs to top-management of my company, so thats alot of mail (4-10gb per mailbox) with lots of subfolders, so that'll be a real pain to move by hands, one can go crazy from copy-paste work needed.
Is there some other workaround to migrate such bix mailboxes?
