The only thing I tried was to remove RPC component rest IIS and add it back. Didn't make any difference.
what else should I check?
thank you
Answer : Unable to connect Outlook via RPC over HTTP
After removing and reinstalling the RPC Proxy component, did you run the Connect to the Internet and Configure Email wizard again? If not then you need to, as the changes it made were removed when you reinstalling the proxy.
