Microsoft-Server-ActiveSync 401/500 errors
Hi All, Just having issues with a Windows 2003 Server/Exchange 2003. When phones are syncing with servers. I am getting the following error: ExRCA is attempting to send the OPTIONS command to the server. Testing of the OPTIONS command failed. For more information, see Additional Details. Additional Details A Web Exception occurred because an HTTP 401 - Unauthorized response was received from Unknown I've got basic authentication only with the domain selected... nothing has really changed. HTTP/RPC is fine. Just Active Sync. Thanks

Basic. Basic gives error 401. Using Basic & Windows Integrated gives error 500 (or just integrated).
