I entered a new task in Outlook which recurs on the Hebrew Lunar Calendar. When I sync, this causes my desktop manager to crash. As soon as I delete the entry from Outlook, desktop manager syncs without crashing. Does anyone know why this happens or how to fix the problem?

Do a search and make sure that you have the required fields for all of the tasks. You might have one that is missing a required field like "status, due date, and/or subject"
