I renewed my SSL UCC certificate and my Self-Signed SSL Certificate for my Exchange Server 2007. Self-Signed expired on 12/25/2010 and my UCC SSL was to expire 12/28/2010.
Now my self signed is valid until 12/26/2015 and my UCC is valid until 12/28/2012.
Since renewing the certificates my Outlook 2007 clients are prompted with a password. However, if they cancel through it, they can still send and recieve email.
When I access their accounts via OWA they work fine and my UCC Certificate is valid.
Is there a way to tell if the self-signed certifcate is causing this problem?
