The owa connetion via the web site is not working on a SBS 2008 64bit server. I can access remote desktop and the companyweb. All users encounter the same problem (shown below). We are using a self signed cert. There no errors shown in the error log. Logon works and the error only occurs when attempting to go to email. I have run the exbpa and the only errors shown are outdated drivers. I have also recreated the owa as shown in the posts as well as verified connectivity and done the fix network shown in other posts. This occurred after an issue that caused a fail over to a file server with GC. That has been repaired and everything else is back to normal. Now where do I go? Server Error in '/owa' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off". <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="Off"/> </system.web> </configuration> Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL. <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web> </configuration>

Hi tprebula, Please reinstall the ASP.NET, restart the IIS Admin service to test. If you configruated the OWA redirection, please temp disable it to test. If the issue still occurs, please rename the web.config to web.config1 to test.
