    I have some very simple tricks to troubleshoot your problem. Please check and confirm whether you have correctly configured RPC over HTTP. Please make sure that authentication mismatch is occurred. Please check whether SSL Certificate is installed on your RPC proxy server. You have to also verify the communication problem between the RPC over HTTP. I will be really happy if the above mentioned suggestions help you.

    Well I was facing the same problem. I was searching on Google read to edit the registry. You have to use Windows Registry Editor Version 5.00. to edit the registry..[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC]"EnableRPCTunnelingUI"=dword:00000000. It really worked for me .According to your situation it may work for you. If it does not work you can go through other forums also. All the best

    Another solution I can give you where you have to again work with the system registry. First of all you should remove Group Policy. If you have system policy then it should be removed after you have to do the following entry in to registry. HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\AutoDiscover. I am providing you next registry detail HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\AutoDiscover This entry should be deleted from the registry. Note that Your System domain administrator will delete the registry.
