When I start Outlook it immediately shuts down displaying following error message: Microsoft Outlook moet worden gesloten omdat er een fout is opgetreden. Werk dat niet is opgeslagen, gaat mogelijk verloren. (I have Dutch version: In English that would be: Microsoft Outlook will be terminated because an unknown error occurred).

Did anyone experience the same and know how to solve this? It worked correct before and it just started out of the blue.

Thank you in advance
