Hi Michael, the Hotfix that you linked is not installable on the system, because our Exchange Server have Exchange SP1 and the files of hotfix are included in SP1. What do you mean with internal? I think you mean by using PocketPC > PC connection. Yes, we can synronize all items by using ActiveSync over PocketPC-PC connection (over Outlook 2003). The log files tell not much. W3SVC1 protocol tells: 2005-04-22 13:07:20 10.10.4.1 POST /Microsoft-Server-ActiveSync User=mustafa&DeviceId=16323330054189E188000050BF3F5173&DeviceType=PocketPC&Cmd=Notify&Log=V2TNASNC:0A0C0D0FS:0A0C0D0SP:1C1I234S1264R 80 hostix\mustafa 10.10.4.254 Microsoft-PocketPC/3.0 200 0 0 Is there any other LogFile on Windows for ActiveSync? Any other idea? Thanks in advance. Cicek
