Here are the facts of my case: running Outlook 2000 on a Novell Groupwise 6.0 server, and my PDA is a Samsung i600 phone. When first installed, I had Activesync 3.7.0 running on the phone, installed it on my PC, and both calendar and contacts synced just fine. My IT department (at my request) upgraded to Outlook to 2002 on my PC, and now the contacts won't sync. And I get the DEV_9 error message. I've uninstalled and reinstalled Activesync 3.7.0, upgraded to activesync 3.7.1, selected and de-selected the settings from both my computer and phone - nothing works. Calendar still syncs fine, but nothing on my contacts. Any help or tips would be hugely appreciated!!!!

This sounds like a Windows Office profile user problem. You may have to create a new profile to associate with your PDA and Outlook. The old profile is probably no longer valid, thanks to the upgrade. Keep in mind upgrading to Outlook 2003 will do the same thing. Since your IT broke it, I'd make them fix it. You can tell them I said so too =) HTH, J.
