I have setup Exchange 2010 and Exchange 2003 in coexistence and everything is working great. As a test I moved my account to the Exchange 2010 from the Exchange 2003. OWA and Activesync worked perfectly. As another test I moved my account back from Exchange 2010 to Exchanage 2003. OWA works, Outlook works but Activesync doesn't work at all.
I have read about a few fixes online and here is what I have tried. I have removed the Activesync attribute from under my user account in ASDI edit. I have deleted the phone in Exchange Mobile Admin. I have even tried disabling and re-enabling Mobile Services under my account. Nothing is fixing the issue
I have a Windows Phone 7 and the error message I get is Error Code 86000108.
Remote Conectivity Analyzer website gives me the error 'The initial sync won't return any data. Exchange ActiveSync command Sync failed with error code ServerError'.
Anyone have any other suggestions?
