Failure phenomena:

After Exchange 2010 restarts, OWA can open, enter a user name and password, and cannot access "HTTP 500 Internal server error", and Outlook uses normal.

Steps to resolve:

Because the server has been changed before, the old server has not been completely quit, and made a long time, success. Turn off the old server before the new year. So I think it will be because the old server has not been completely invalidated, and then start the server, the failure is still.

Because Outlook can be used, so can be identified as the Outlook WEB app problem, and the homepage can open, just enter the password after the prompt error, HTTP500 error is generally the service did not start, and the error page directory is Auth.owa, Should be a Web authentication error. So in the control Panel find, found MSEXCHANGEFBA not up, the service information as follows:

After the service is started, it can be accessed normally.

You can restart IIS to make sure that it takes effect.
