Yesterday we replaced our 2003 server with a 2008 server. I transferred the FMSO roles and there didn't seem to be any problems. I haven't even shut down the 2003 one yet. Our Exchange server is on another 2003 server. Apparently now none of the mobile phones/Ipads can sync email now. I have to assume that was the cause since the timing matches up and that's the only thing that has changed. Exchange seems to be running fine and there are no errors on it. Can anyone think what I need to do to fix this I have an Active sync tester I downloaded and when I use it I get this error
ActiveSync detected, but not correctly configured. [HTTP 500: Forms-based auth enabled?]
It was correctly configured before we changed domain controllers.
