If this looks familar you are right.  We’ve blogged this before.

But BEFORE you get to this step and start ripping out Exchange installs… what are you planning to do with email in SBS 2011 Essentials?

I hope you said “oh we’ve contacted a hosted email company and they said to do this…” not “Oh, you mean Office365 is not included in the SBS 2011 essentials?”

In software there is a lot of moving parts and no where no noticable than SBS where the system has to wait for the parts to RTM… or not.. in the case of SBS 2011 Essentials.  Right now there isn’t even a public beta of Office 365.

Now … let’s also be honest .. in the consultant community the idea that Microsoft is going to bill your client is less than palatable in these parts.  So many are looking at www.ownwebnow.com and other hosted email vendors.

If you add user accounts after you move mailboxes to the Destination Server and before you uninstall Exchange Server 2003 from the Source Server, the mailboxes are added on the Source Server. This is by design. You must move the mailboxes to the Destination Server for all user accounts that are added during this time. Repeat the instructions in Move Exchange Server mailboxes and settings for Windows SBS 2011 Essentials migration before you uninstall Exchange Server 2003.

You must uninstall Exchange Server 2003 from the Source Server before you demote it. This removes all references in AD DS to Exchange Server on the Source Server. You must have your Exchange Server 2003 media to remove Exchange Server 2003.


To remove Exchange Server 2003 from the Source Server, follow the instructions in How to remove Exchange Server 2003 from your computer.
