what are some ways to move a handful (30?) mailboxes to a existing exchange org on a completly different domain.
Site A = my domain, seperate physical site
Site B = seperate domain, seperate location (to be demoted and rebuilt as part of our domain)
due to the small amount of use i think it makes more sense to move the mailboxes to our site on an existing exchange server.
Recreate all users accounts. then somehow re-attach the mailboxes to the new user accounts.
Please provide ideas (maybe multiple).
