  (*Final Answer*) OAB issues after simplifying the OWA 2010 URL? http://blogs.msexchange.org/walther/2010/03/22/oab-issues-after-simplifying-the-owa-2010-url/ http://social.technet.microsoft.com/wiki/contents/articles/simplify-the-outlook-web-app-url-in-exchange-server-2010.aspx     http://social.technet.microsoft.com/Forums/sk/exchange2010/thread/0e2e73a1-73ca-4d0c-a5a3-3434be8ebd73 Perhaps you are seeing the same thing.  Check the OAB directory (%ExchangeInstallPath%\ClientAccess\OAB) for a web.config file.  If it exists you can do one of two things.  Delete it (I usually rename it) or grant NT Authority\Authenticated Users READ access to the web.config file. You may have to reset IIS after making the change; not 100% on that.
