Issues connecting Outlook 2010 to Exchange 2003 via RCP over HTTP

Hello, we have never had any issues connecting our remote clients to our exchange 2003 server via outlook 2007. However, now that we are starting to implement office 2010, we have not been able to conect any of these 2010 users to our exchange 2003 server via RPC over HTTP. We go through all the usual settings as far as configuring all the connection settings in the same way we did with our outlook 2007 clients - however we get an error saying that the exchange server is unavailable. It seems that this is a widely known issue but I haven't been able to get an answer on this. Please help.

On the account settings in OUtlook, when you click more settings, under the Security tab uncheck the "Encrypt Data between Exchange and Outlook" check box, restart Outlook and see if the problem persists.

Are you using a self signed or a 3rd party SSL certificate?

We are using a self signed cert and I have installed that self signed cert under the trusted root. I just attempted unticking "encrypt data between exchange and outlook" and that did not appear to make a difference.

if you are using a self signed certificate then this is going to cause problems because it probably won't be a SAN/UCC certificate with the correct names in.

See the autodiscover section of my article here for the correct names to use: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2300-Outlook-continually-prompting-for-username-and-password.html
