That sounds suspiciously certificate related but why dont you get through this doc or something  like it and see if you can provide more detailed information.

Do you have mail boxes on the 2003? if you move them to 2010 does the situation change? what are the errors? try testexchangeconnectivity.com and https://testexchangeconnectivity.com/ and let us know the results of that testing.

thanks L

The link  was provided to show you the types of things to provide. There are several things needed to answer this question properly. 1. Ure you using outlook anywhere whe you say internal? Does your UC SAN have the internal URl on it ? Does the Connection point have the proper internal url setting? I need to know more about the goal before I can give you an A answer. Here is another example

Can you provide the method you are using to coneect internally, along with certificates information? even the results ot ttp://testexchangeconnectivity.com would give me something to go on.

Thank you,
