How to refresh an outline?

I am replicating my mail with a POP-Server. Since mailrules do not apply then, I wrote an agent that puts all incoming emails into the right folders. This works fine so far, BUT:

After moving the documents to the designated folders I want to refresh my outline showing in each folder, how many unread (new) documents there are (You can see this, when you get new eMails. Then the Inbox in Notes 6.x turns bold an shows in brackets how many unread documents there are).

So is there any way to refresh the outline or at least the page the outline is embedded in? Help would be appreciated.

TIA,

Gernot.
