Thanks Michael, Would it make any difference if the two domains had a two way trust (merger)? regards, Paul. ________________________________ From: listsad...@lists.myitforum.com<mailto:listsad...@lists.myitforum.com> <listsad...@lists.myitforum.com<mailto:listsad...@lists.myitforum.com>> on behalf of Michael B.

There is no Microsoft way to do this. (Well, other than exporting each mailbox by hand, etc. etc.) You need a third party tool. Transend, Binary Tree, MigrationWiz are the 3 I've used most recently.

Hi, I have two Orgs with there own domains, both using ADSync. I need to move the users from tenant A to tenant B 365. I would use MDT for the AD accounts. How would I move the mailboxes? Any information would be appreciated. Regards, Paul.
