AD replication delay and provisioning tasks ...
We're moving mailboxes from one Exchange server to another.
Before doing the move, we add them to a non-archiving group, then remove them after the move.
Obviously we can't tell exactly when the move will be finished.
Our provisioning task runs 1 hour before the auto archiving.
1. What happens when the provisioning task runs, AD replication has not yet completed and AD says that the mailbox is still on the old server?
2. Most of our provisioning group targets are "all mailboxes on server x", in that case does EV query AD or the Exchange server itself? A few exceptions use group membership.
We have a couple of AD sites and replication can take a while.
Thanks for any advice.
