HI I am trying to do a cross forest migration of mailboxes. I have everything ready to move the mailboxes and it does it's prepare and addx the x500 to the source and the linked mailbox as a test i created the same distribution group at the destination forest and saw it put the user in the right group on the forest but anyone that is still left in the source organization can't send to those distro groups it bounces back since it doesn't know how to route to that distro group. what is the best way to handle this in the period of the mailbox moves
Thanks,
