We are in the process of migrating our Server 2000 with Exchange 2003 to Office 365
I have got through most of the set up but the last error i am now receiving when running the Remote Connectivity Analyzer is :-
Testing HTTP Authentication Methods for URL https://exchange2.creditfixme.co.uk/rpc/rpcproxy.dll?exchange2.creditfixme.co.uk:6002
The HTTP authentication test failed.
A Web exception occurred because an HTTP 501 - NotImplemented response was received from Unknown.
On the server the RPCProxy folder is empty and in IIS there is no RPC under Default Web Sites. Is this something i need to install and if so how?
I have also attached the full document from the Remote Connectivity Analyzer. Any help would be fantastic.
