I have lots of problems with the outlook connector on both outlook 2003 and 2007 where it suddenly dies resulting in no updates in outlook. To resolve the problem I usually have to shutdown outlook kill the outlook process in task manager and the finally restart it again.
Is this a known bug with the outlook connector for version 5.0.4 and 5.0.5 cause I've had the problem for quite a while now. I have not tried the 5.0.6 version yet, thought that I skip this release and go straight to 5.0.7 instead.
Uninstalling and reinstall the outlook connector does not seem to help, tried that a few times.
I just hope that the next release will bring some more stability to the outlook connector.
