We recently installed Exchange 2010 and everything was working well including the owa access. We encountered some problems with log files filling up the drive and after dealing with that issue we can no longer access the Exchange server via owa. Please see the attached file.

Looks like you're running SBS (2011?). Did OWA go down as a result of the log files filling up your volume?

Have you checked all services that are set to automatically start on the SBS? Have you tried an iisreset from command line? Is OWA accessible internally from your SBS? (try https://localhost/owa from your server).

OWA went down after the log files filled the volume. OWA is not accessible internally - get the same error message. The iisreset did not solve the problem. The logging problem was fixed by changing to circular logging.

In the error you were advised to include the customerror= Off. Once you do this what does the error page show now?

Can you access OWA via standard HTTP (internally)?

Ok, that's actually by design. I don't think you can access OWA (Exchange 2010) without SSL/HTTPS unless you go into IIS and change some things.

Would this problem be related to the "web.config" file?

In your pdf it is the first yellow position.
In other words directly under the first <system.web>

Be aware, the line is case sensitive.

Take backup of web.config file.
Rename existing web.config.bak file to web.config and restart IIS
Check owa.
