(Exchange 2003) Outlook Web Access and firefox

Figured it out and am answering the question to help others that may be making the same changes. When migrating from a regular certificate to a wildcard certificate you must change the MSSTD (principal name in Microsoft-Standard Form) in the MS Exchange Proxy Settings and ensure that IF you have a principal name set you'll need to change it. In my example since I was migrating from a regular cert to a wildcard I had to change it from:

msstd:webmail.domain.com to msstd:*.domain.com

After that change everything worked like a charm!

Edit: This is a setting done on outlook clients prior to 2010. You find it under Connection -> Proxy Settings of the users mailbox

Try this: Create a new Outlook profile with the same account settings. I´ve got a similar problem a few weeks ago. After i created a new profile it worked.
