I am attempting to move 3 mailboxes at the same time within powershell via the following command:get-content move.txt | move-mailbox -targetdatabase db03 -maxthreads 3Generally I think this would then move all 3 mailboxes at the same time but it ends up only moving 2 at one time.I also tried the same move-mailbox command without the -maxthreads paramater and it still only moves 2 at one time.This happens in all cases, no matter how many mailboxes I am trying to move. I have tried moving 10 at a time with a -maxthreads 10 but it only picks up the first 9.It appears that it will look at the number of mailboxes listed in my txt file and grab one less that the max I stipulate.Wondering if anyone else has seen this issue.Thanks.Mike
