Question about Outlook Express

I´m having trouble with tasks not showing in Outlook. (they are visible in the web-version, but not in my client installation).

I tried to create a new identity, but that didn´t work.

Since the tasks are visible in the web-version, I´m suspecting that it is a check-box I missed somewhere so the tasks are not visible, though I´ve tried just about every different setting I found.
