I installed exchange 2010 sp1 in an Hyper-v environment. I had to move 25 mailboxes. 23 moved with no problems. the last 3 mailboxes (the largests) with 12, 14, and 18 giga are painfully slow, even 1 by 1. it took me 12 hours to do 50% of only 1 mailbox. and its getting even slower. i dont really understand whts happening. Do someone have an idea. did i something wrong?
