SBS Server: Remove / Uninstall Exchange

KB ID 0001455

Problem

I’ve never really been a fan of SBS Server, Theres too many ‘wizards’, and things that are either automatically configured for you, or wont work until you’ve configured something else, I’ve a boat-load of problems with it over the years.

Last week saw me retiring an SBS 2011 server, and migrating to a 2016 domain, with Exchange 2016 server. But how to gracefully remove Exchange 2010 from the old SBS server?

Solution

Firstly, SBS or not, this is in essence just an Exchange 2010 to Exchange 2016 migration, and all the methods and prerequisites are the same. I’ve covered that entire procedure before in the following series of articles, go there and run though them and then come back here when you are ready to uninstall Exchange 2010.

 
So you’ve gone though the above procedure at this point? Anyway to summarise, make sure before proceeding that;
 
  • All 2010 Mailbox Databases are dismounted and removed.
  • All 2010 Public folder Databases are dismounted and removed.
  • The 2010 Exchange Server is NOT responsible for any Offline Address Books.
  • Open Toolbox > Queue Viewer > Make sure the queues are empty.
  • The server is NOT set as a source server on your ‘Send Connector’.
  • The 2010 Exchange Management consoles are CLOSED.
Open and Administrative Command Window, then navigate to the folder that Exchange is installed into and change directory to the ‘Bin’ directory, (in most cases this will be on the C: drive). Then use the command line option to remove Exchange;
cd "C:\Program Files\Microsoft\Exchange Server\V14\Bin"
setup.com /mode:uninstall

Uninstall Exchange 2010 from SBS 2011
