Is there a way to change the length of the recently used categories in
Outlook 2007? It shows 15 but I'd like to increase it to 30 or 40
since4 I have a high resolution monitor and I use categories
extensively.

The "recently used" list I refer to is what pops up when you click on
the little four-pane "categorize" button on the toolbar.

Any information leading to any way of doing this or leading to any
tools that make categorization easier would be greatly appreciated.

Thanks!
