So we have an Exchange 2010 single server environment set up at a small company where I do IT work. I installed Exchange 2013 into a separate virtual machine to begin learning it, and now some of our Outlook clients are popping up randomly with a security error message. The security error complains about autodiscover.ourdomain.com and the message is:
"The name on the security certificate is invalid or does not match the name of the site"
I didn't tell Exchange to do a single thing other than install itself. Everything was fine before installing Exchange 2013. Why would simply installing it make disruptive changes? *slightly annoyed at this behavior*
