Exchange 2013 - Accidentally installed Client Access role on new Mailbox server - users get certificate pop-ups
Posted on 2016-11-17
Installing a new mailbox server but accidentally installed Client Access Role too. As soon as the installation neared completion users started getting certificate errors from the new server.
1. Don't understand how this can be. We point all our clients to a load balancer which points to our existing CAS servers so I don't understand how outlook clients can see this new one.
2. Server is offline now because of the problems its caused. How do I remove the CAS role from it? I assume I need to be online to do this properly (so it can access AD)? Will need to do out of hours I guess.
