Hi All, I am in the process of migrating users from Exchange 5.5 to 2003. I have the necessary trusts in place and the ADC set up for 2 way connection agreements. The 5.5 server is in a seperate domain (old NT4) and the users have been migrated to the new 2003 domain. The trouble is that when I click on exchange tasks for AD users with mailboxes on the 5.5 server, I do not have the option to move the mailbox. can anyone point me in the right direction? Thanks TD
