We have an existing exchange serve installed on a domain controller. We have installed a new member server and then installed exchange onto that. We have migrated all the mailboxes and I've followed the Microsoft kb 822931 on removing the first exchange server.
My question is that the only remaining (new) exchange server is only a member server, and the exchange removal is looking to modify the forest prep etc.
Will removing exchange from the DC cause any problems to the email?
