I have a single Exchange 2010 server configure in the same organisation as two Exchange 2003 servers. The Exchange 2010 server is working fine in terms of mail flow and OWA. However I can't get Outlook anywhere to connect from remote Outlook Clients.
Running the remote annalyser I get the following results, any help would be great, I'm lost as what to do next.
Testing RPC/HTTP connectivity
RPC/HTTP test failed

Please see below a list of articles that might point you in the right direction. I myself I would start by disabling IPv6 if that one is still enabled on the server. Then I would do a netstat -ano on the Exchange server to see what ports are open and who's litening on them .
Hope it will help.

Please try to use Exchange Remote Connectivity Analyzer Tool from outside the network to check the issue.
Besides I’d like to collect some information with you:
1. Please run Get-OutlookAnywhere |fl and then post here.
2. Please run Get-outlookprovider expr |fl and then post here.
3. Please try to run https://domian.com/rpc/rpcproxy.dll and then post the result here.
4. Please check settings on RPC virtual directory, if any redirection has been set there.

I actually managed to fix it myself, your point 4 is where the problem was, I had the RPC directories pointing at OWA for some reason.
Many thanks for your help, if I hadn't of already sorted it, your reply would have.

I am having the same issue. When I ran the MS connectivity analyzer, this is what I got:
accept/require client certificates isn't configured.
Client certificate authentication wasn't detected
My configurations -
The cas server authentication method: NTLM
ISA server authentication method: basic
Outlook Client authentication method: Basic
Not sure what I did wrong but the Outlook client can't find the server
Any help would be greatly appreciated.
