We are having an issue after we upgraded to Exchange 2010 - all of our Outlook 2007 and 2010 users get 2 security alerts when they start Outlook. The Error says:
The name on the security certificate is invalid or does not match the name of the site.
Once the user clicks yes twice everything works (Execpt for Microsoft Exchange offline address book - which i believe to be related)
Our internal domain name is different from our outside domain name - which is where the problem is I believe.
I believe that powershell will be involved - but I am no Exchange Guru and I am not quite comfortable with poweshell enough to go adding some code to my certificate. Can anyone help?
