I am currently testing a Windows Server 2008 R2 with Microsoft Exchange Server 2010 Standard to replace our current Windows Server 2003 Small Business running among other things an Exchange server for 15 persons.
The new server works great as long as I use Outlook or the web interface however when I try to connect a HTC Hero the phone has problem syncing. Mail and contacts sync just fine and the calendar syncs fine as long as it is empty but as soon as I try to import the file I exported from our old server it stop syncing.the calendar.
It seems though that if I use an empty calendar and create new meetings those sync very well, also if I move all the imported objects to a temporary calendar and just move certain old meetings back to the calendar it seem to work. Approximately half of the old meetings seem to be ok but the other half seem to break the sync. I cannot find any pattern to which objects break the sync, it can be anything from repeating meetings to a plain meeting with only a simple subject without location, description or invited people.
The very helpful error message I receive is "Synchronization is experiencing problems."
Anyone here who have had this problem? Or anyone know if there is some kind of tool that could identify the problem and correct it?
I have tried with two different phones on two different accounts with the same result
The server tests ok on the testexchangeconnectivity-site and the problem appears both with and without SSL in the server and the corresponding setting in the phone.
