Thinking out loud on options.
The original CAS is still in the domain, but Exchange is not installed. Can I/Should I reinstall the CAS role? Or I could nuke it completely and rename the new CAS to match? Another option is to just suck it up on Monday. My Outlook users are concentrated at two buildings, I could have two people at each of those buildings and they would all be fixed in an hour. Stragglers at other buildings could be handled by remote by the remaining tech staff. Not the end of the world since web mail still works for them...... I hate to script delete their profiles with no testing.......
