Installing Active Directory Synchronization for Office 365

Last Modified: 2015-03-12

We are currently at the very early stages of migrating Office and mainly Exchange mailboxes to Office 365.

I have found one implementation guide that states you have to completely remove the on premise exchange server (Exchange Server 2003) from AD as a prerequisite before installing and configuring ADSYNC on a server  but can't find this stated in any other guides.

Not sure how you would then move the mailboxes.  I have already backed up Exchange and exported mailboxes to PST.  

Does anyone know if this is correct?  I only have about 30 mailboxes to move.

Many thanks
