I have a simple environment. A Server 2012 R2 as a DC, and 2012 R2 running Exchange 2010. We recently had to renew our SSL cert. When I migrated this from an earlier 2003 AD I did not give any thought of moving from a .local to a .com domain.
Now we have run into the magical SSL Cert error when people open Outlook due to the whole SSL SAN issue.
I am thinking that renaming the domain to a .com suffix is probably easiest....
What considerations do I need to take into account with me Exchange server?
