I have been transitioning our environment from 2003 to 2007. I am at the point where I am trying to get our Droid users to be able to sync with our Exchange 2007. They were all able to sync with our 2003 exchange FE using the same certificate. When trying to connect to the 2007 exchange server, they get a error, "The certificate from the server is not validated." If I uncheck, "Verify Certificate" it will sync.
When I go to our OWA webpage at: https://webmail.mydomain.com
I get no certificate error at all using a web browser. I feel there is something I have over looked and haven't been able to find much from searching the web. Thanks in advance,
