We were having problems with our OWA website not displaying the normal logon page. It would bring up an authentication box separate from the page. We were able to authenticate. At the same time, we started having problems with our users and free/busy, shared calendaring, public folder items. This all pointed to the autodiscover record.
I was able to delete the OWA virtual directory using Exchange Management Shell. I then recreated the OWA virtual directory using Ex Mgmt Shell. This has resolved the issue with the OWA site. It now correctly displays the page. However, Autodiscover still did not workproperly.
When I went to the /Autodiscover website URL, it brought up a message "server error in application OWA-FBA". I thought I would be able to reinstall that virtual directory as well, but have not been able to find instructions on how to reinstall OWA-FBA. So as it stands OWA is working, but Autodiscover is not working.
Can anyone please tell me how to reinstall the OWA-FBA virtual directory in IIS on Exchange 2007?
