Information Worker Behavior

Just wondering if anyone else has had similar issues with IW.

Things like CRM calls can be initially imported into Outlook, and stay there
while offline, but as soon as an update/sync is done they all completely
disappear from the outlook view.

Anyone run into this and know of a solution or what the cause might be? I
have not found any settings that appear to control the retention of things
in Outlook.

Same thing happens with tasks, appointments, customers, etc.
