Hello,
Last week, the user's Outlook clients started getting persistent pop-up messages when connecting to Exchange server 2013 on server 2012.
The pop-up security alert stated the security certificate is from trusted certifying authority. The security date is valid, but the security certificate does not match the name of the site.
I clicked View Certificate and installed the certificate successfully. The next day it pop-up again.
Can someone help me?
Jimmy
