How to test RPC is working?

I have a new exchange 2007 box on Windows 2008 R2, email is flowing internally and externally.  Outlook Web Access is working fine.  I would like to connect my iPhone and Outlook 2007/2010 to our server for email connectivity.  When I setup the Outlook client, I add the internal IP address as the exchange server, my username, I insert the correct settings in the Exchange Proxy settings, but cannot get the clients to connect.  

What are your thoughts on this?  What should I look for?

Thanks in advance for your help.

Did you purchase a SAN / UCC (Multi Name) SSL certificate from a 3rd party SSL provider such as GoDaddy or are you using the Exchange generate certificate?

Also, I dont have my internal domain as exchangsvr.adsvr.local I have it as exchangesvr.adsvr.com


does that cause a problem?

Alan HardistyCo-OwnerCommented:
Okay - for starters - you need to re-key the certificate and add the other names I have mentioned otherwise you will get certificate errors.

gk2incAuthor Commented:
OK, working on the re-key.  Might take 2-24 hours..so GoDaddy says.

Alan HardistyCo-OwnerCommented:
Yes - they would!  Adding internal names should be a quick process involving them sending you and email and you approving the email.
