"Unable to Verify Certificate"

I got my iPhone 3G yesterday and I'm trying to set it up with my exchange mail. When I go to set it up, ActiveSync tries to do an automatic configuration. It returns "Unable to Verify Certificate" "While automatically discovering account settings, the certificate from "xxxx.com" could not be verified."

When if click accept, the server field shows up, I enter my companies OWA web address, "owa.mycompany.com" I get "Verifying Exchange account information", followed by verification failed. I've tried it with and without my domain, "mydomain\username." No luck.

Our company provides OWA and OMA access and I can access OWA through Entourage.

What am I doing wrong?

Another vote for the same problem. I installed the Exchange 2003 certificate on my Iphone after emailing the certificate to another e-mail account. Exchange e-mail still does not work on the Iphone. No e-mail, calendar, or contacts.

We found a solution to why exchange was not populating the iPhone once we had set-up Active Sync with Exchange it was due to this reason...

I had the same problem. Set it up as SMTP instead of exchange then once the account is set up Turn off SSL. In advanced settings I had to turn on AT&T SMTP so I could send mail. Now it works fine.

We were using SSL just fine. Then something happened... any other ideas what this could be?

It's affecting 2G and 3G phones alike.
