The Outlook Connector fails to connect showing the error "HTTP 400 - Bad Request" in combination with Forms authentication.
20121204 or newer
Note: This is not a generic issue and it does not occur in all environments. The user who encountered this error was running MARC on Windows 2003 64-bit with SharePoint, and OC on Windows XP with Outlook 2003.
To identify this issue, check the following items:
- Confirm that the Forms Authentication is in use on the MARC server.
- Open the web interface in a browser and confirm that it loads correctly.
- Confirm the OC debug log reading:
2013-01 31,15:45:34,540,1,"#00000da0","#00001534","warning","logmartransport","TransportManager::Connect The connection failed hr = 0x80004005 - HTTP error: 400 (Bad Request)."
- If possible, configure the server to use Windows Authentication.
In this case, the OC should connect successfully. If the issue is not fixed, please contact support.
Note: Patches are not available for supported MARC versions.
