How does a task know it's assigned to me? (WSS3, Outlook 2007)
 

I have installed a Windows Sharepoint Services 3 site on a server and
have installed Outlook 2007 on my laptop. I set up a task list on the
site and then open in it Outlook. If I assign the task to me, it shows
assigned to me on the site and in Outlook, but it wont show up in the
To-Do List or To-Do Bar (or on my calendar).

The documentation I've seen online says that the task will show up in
those lists if it is assigned to me. How does the task know it is
assigned to me?

Is there a way to modify the filtering of the To-Do List/Bar/Calendar
so that I can force it to show tasks assigned to me?

Other info...
We do not use Exchange. All users are set up with POP accounts.
I work remotely and VPN into the company network. I log in locally on
my laptop.
The user account on the WSS site shows me with my main POP email
address. In Outlook, the task shows up with my name and POP email
address.

The WSS3 and Outlook 2007 integration is great! I'm hoping that this
anomaly is something small I've overlooked.

Thanks for your help
