I still see a lot of activity in Exchange 2003 and 2007 forums online so I thought it would be interesting to see which version of Exchange Server the readers of this site are running at the moment.  Please cast your vote in the poll below.

Note: if you’re currently in the middle of a migration project just choose the version that you’re migrating to right now.

If you’d like to provide a bit more information about which version you’re running and why please leave a comment below.

    Would be interesting to update the poll, see what kind of penetration Office 365 has at this point. For my company, it would be a mix of Exchange 2010 and Office 365 right now.

    Great blog Paul. Your work is valued in the Exchange community. I fall outside of your poll as i run a variety of email servers concurrently. BBS (Citadel), Postfix, Open-Xchange, MS Exchange 2003. 2007 and 2010.

    I’m on the tail end of a massive mail migration… Started with ~2000 users on a BSD/Postfix box, as well as 500 users on Exchange 2003. Have been working on this as a zero-downtime method since early January. I’m about two weeks off having all users across to Exchange 2010 SP1.

        Seriously though…the IMAP protocol can die in a fire.
