"HTTP/1.1 500 Internal Server Error" when accessing OWA frontend server
|Cause||After implementing SSO into OWA in a FE/BE scenario (IIS6 with protocol transition) by following the instructions in the agent's manual and solution How to configureOutlook Web Access (OWA) with front end and back endservers for SSO using ClearTrust, users attempting to SSO into OWA on the FE receive an "Internal Server error (HTTP 500)", right after having passed Access Manager's authentication.|
|Resolution||Please ensure that the domain account configured in the IIS's "Directory Security" settings in order to grant anonymous access to the /exchange, /exchweb and /public directory on the FE does also have an Exchange mailbox.|
If needed, create a mailbox for that user using the appropriate Exchange tools.
