We upgraded Exchange 2010 SP2 from Exchange 2003 in 2012 and all has/is working as expected
I installed a new Exchange 2010 Enterprise server in a 2nd site with Mail, HUB, CAS roles
Now users in this site are getting Security Alert(s):
"The security certificate was issued by a company you have not chosen to trust. View the
certificate to determine whether you want to trust the certifying authority."
I took the defaults while installing the new server and no configuration has been done
