Outlook SSL Certificate Error

Hi All,

When our Outlook 2010 users log in they are greeted with a certificate error.

Any idea how I can get rid of it.  I'm comfortable deploying certificates via group policy (if that helps)


Many thanks

make in youre internal dns an srv record _autodiscover _tcp port 443 and enter te name the autodiscover url in youre certificate. also be sure you make dns entrees of youre external owa and autodiscover point to the local ip of youre exchange server.

You can add internal FQDNs but as long as they do not end with .local.
e.g. servername.mycompany.com
