I've been unable to get Outlook Anywhere to work for any remote clients using Outlook 2007. I have an Exchange 2007 server on my relatively small domain and it is connected with 1 nic to my network with an internal IP and the 2nd nic is connected with a static address to our ISP (probably unsafe but was having trouble getting this to work otherwise).
Everything internal works fine (however we get a certificate error whenever outlook is launched because our certificate is for *.domain.com and the server is exchange.localdomain.local
). This is an issue I will address at another time since it at least works. Remotely our OWA works great and is running over SSL with the proper cert.
I went through exchange_genie's howto at:
and verified all the changes. RPC over HTTP is setup, it is listed in IIS 7, RPCProxy.dll is allowed, I used EMC to enable Outlook Anywhere, with Basic Authentication and verified all the Valid Ports in the registry.
Outlook itself from outside the company is setup using exchangeserver.localdomain
.local and the connection tab has outlook anywhere's option checked off using SSL only and Basic Authentication.
My mind is a bit mushed up now so if anyone can think of some alternative ideas to check - that would be great!
