Exchange migration 2010 from 2003 autodiscover problem

Hi attempting to migrate exchange 2003 to exchange 2010

Using legacy.company.com in external dns

When mailbox is on Exchange 2010 autodiscover (from connectivity test website) activesync, autodiscover works. When mailbox on exchange 2003 autodiscover fails to resolve and tests fail. What should I check?

In lieu of little information, I would suggest... that you use the proper tool to diagnose what is wrong.

Here is the link for the proper tool:

You can drill down into the results and see exactly what is failing and why... AND it will sometimes give you links on what to fix.

Thanks-
I was using the website....badly. My question wa not clear at all so thanks for the help.

My main issue was Outlook Anywhere. So to do the test since it is for a mailbox on Exchange 2003..I assume I would:
Have to manually enter the server info.

When I entered info manually it was failing on HTTP authentication. Changed it to Basic and it passed. Now I can check what was being used on the Outlook client and make sure it matches.

Thanks!! Now to finish hitting my forehead because I am an idiot
