I have since this morning the strange thing that when I open Outlook 2007 (with latest updates) Koffbackend.exe keeps running and takes up to 80-90% CPU. Confused
Only with Task Manager I can stop this service.
KerioConnect 7.2.3 installed with Offline Connector on client (Windows 7 32b).

Anyone a suggestion how to fix this?

After I reinstalled Koffconnector it seems to be solved but when I check in Task Manager, Koffback still uses 40-50% CPU processing.
It seems that this is normal in the beginning to synchronize all items. After A while CPU uses only 2-5%.
