Autodiscover only working for a few users

[jcrapps]

Hello All,

I'm having a weird issue at the moment. I have created an account for a couple test users for my Exchange Server and when I log in to their Outlook 2007 accounts, I get the Certificate Error message saying that the site name does not match with the certificate. This is fine because I don't have a SAN. Everything works well with these clients. I don't get an error message in the Sync Issues folder and I'm able to DL OAB and use OOF in Outlook 2007. With ALL other users, when they start Outlook 2007, it doesn't give them this Certificate Error. They aren't able to use OOF, OAB, and get an error saying the URL for OAB is incorrect. Is this a permission isssue? I'm not sure where to start.

That's actually not why. A SAN certificate it not required to get rid of that prompt. The certificate merely needs to match the name in the URLs. See my detailed response in thread1582-1474625

Thank you, but my issue isn't the certificate error, it's the fact that most users can't use the autodiscover functions like OAB and OOF.

Fix the certificate errors, since Outlook 2007 uses web services in Exchange 2007 (hence, a certificate) to get the OAB.

Outlook 2007 uses BITS to get the OAB.
