Hope someone could help me to solve this. I tried to load a Service Pack 3 for an Exchange 2007 on a 2008 Server. There was a fatal error during the installation (please refer to the log below). So I did a restoration from a Full backup I made prior to the update. After restoring and restarting the server, OWA is messed up. I have to type in the full URL https://mail.domain.com/owa instead of https://mail.domain.com to get into owa, and the OWA webpage is loaded in a plain text mode without proper logo or background etc. Hope anyone could help me how to solve this.
