I have been struggling to fully set up my exchange 2010 server, whilst webmail, and outlook clients work. Activesync and outlook anywhere (rpc over http) do not work.
I am however using a wildcard certificate for this domain initially to test co-existance, and functionality.
My email addresses are user@example.com however, my configured webmail/activesync/rpc proxy is examplemail.com. I cannot change this. To get around the auto-discovery issue, I have an a record from autodiscover.example.com to a external ip natted to a sepetate ip on my network adaptor, then iis to redirect this to the right place. this appears to work.

I plan to alter dns of examplemail.com and legacy.examplemail.com so that ip addresses make the legacy server the 2003 server and the examplemail.com server is the 2010 one.
Currently in testing I am not using a UC/SAN certificate, however, if i were to swap the ip addresses round so that examplemail.com was the new 2010 server, could i use a standard ssl cert as it is redirecting autodiscover to this address?
Or do i have to get a uac?
Currently in testing using the wildcard cert, for domain (webmail.examplemail.com) rpc over http is not working, exchangetest.com says it cannot ping the endpoint (6001).
Although locally on my server rpc ports are listening, and i can do an RCPPing and successfully connect, the rpc side is all set up 100% correctly.
is this expected behavior if the cert is not UC/SAN and a wildcard instead of mail.examplemail.com?

Any help would be appreciated!
because im having no luck...

For the activesync issue this can indeed be caused by the wildcard certificate if using an old Windows Mobile device. Since version 6.0 and above it should not be an issue.

About your configuration I am doubting it it supported with these kind of tricks. To perform a correct test you will need to directly NAT the Exchange 2010 server behind the external IP address. After that use www.testexchangeconnectivity.com to perform the tests and post the outputs here.

is this a single multirole server or do you have seperate CAS/hub/MBX Servers?

I have had this where the mailbox and the Cas role are on the same server, causing the loopback to not work properly.

If you go into your hosts file, and make a manual entry for the name of the server itself, pointing to the correct IP Address and try again, this solved my issue with a multirole server.

If you have single role servers, check windows firewall is not blocking the traffic and that if you do use the firewall, you used SCW to correctly configure for exchange.
