I recently upgraded our exchange from 2007. I put exchange 2010 on a new server, I moved all mailboxes to the new server. I have the internal and external settings in all of the services. I have my SSL certificate installed as well as a self-signed certificate. I am ready to decommission the old server. I still have one problem though.
My active sync users can no longer connect. I have tried to do an Exchange connection multiple ways. With the iphones it just hangs on 'verifying' or with the androids it just keeps trying to 'sync'. I am running out of things to try, I have researched and researched.
Does anyone know how to fix this?
Does having both servers still coexisting have anything to do with it?
What do I need to do to completely get rid of the old servers in the domain? (Looks like there is reminisce of an old EX 2003 server as well)
