Firstly, this is only affecting wireless sync, Outlook works perfectly.
We're running Kerio Mailserver 6.3.0 and we're taking advantage of the Mobile device support.
One of the users has a Bluetooth enabled iPAQ running Windows Mobile 2003. We got the thing wireless syncing beautfully ie. Inbox, Contacts and Calendar. It was working a treat.
The problem now is that there was an issue with the ipaq so we restored the ipaq to a working state from a previous backup, now we can't sync Calendar entries for that user (this is NOT a public folder calendar, rather a private calendar associated with the username.)
I checked the error logs on the server and I see this:
[09/Feb/2007 15:30:29] FolderName.cpp: Empty folder name (user=<email address>, protocol=HTTP)
[09/Feb/2007 15:30:29] ASyncAirSync.cpp: ActiveSyncAirSync::ProcessCollection: Unable to open folder with CollectionId: 662a6505-cd2d-44c9-9419-6e50e4cd2687
If we untick Calendar from the sync list, Inbox and Contacts work, but as soon as we tick the Calendar box to sync bang! we get errors.
I understand someone else was having issues with public folders with the same errors but there was no solution apart from "you can't sync public folders." Since these are not public folders AND the fact it was working baffles us.
We tested a Windows based USB ActiveSync and the calendar sync'ed no problems, but as soon as the wireless activesync is enabled it stops working.
The error on the iPAQ activesync is:
"Synchronization failed. Try again, and if thhis condition persists, reset your device.
Error code: 0x80004005"
I've reset the thing and it makes no difference. I don't understand the "Empty folder name" from the error as well.
Anyhelp is appreciated!
