Outlook web access (OWA) gives 404 error from Exchange

OWA (Outlook web access) is mostly working very well, and when its not the Exchange server itself is down.

Until a few days ago. I received an email from a college who was unable to access the webmail from home.

I had the same problem after checking, so I thought the Exchange server or internet connection was down.

Strange enough there where still email coming in, and I was able to send mail to my private account. (No internet or Exchange failure!).

Internet explorer gave me a normal 404 error, Firefox said “Data transfer interrupted” witch was different then a 404 but i never saw the error before.

The steps I did to fix:

Reset (recreate) all website files for the OWA.

See: http://support.microsoft.com/kb/883380

And also I recreated the SSL certificate. For some reason I was not able to view it any more.

See: http://www.petri.co.il/configure_ssl_on_owa.htm for creating a (new) SSL certificate and use it for OWA.

After I did both steps, it was working again in Firefox but not in Internet explorer!

IE freezes at “Loading”.

Microsoft knows this problem:

Force a SSL connection:

Now it was working like a charm again! :-)
