Mailbox Size in Outlook Toolbar or Status Bar

Are there any utilities, add-ons, scripts, etc that can place a small text box on my MS Outlook 2003 toolbar that displays my total MS Exchange mailbox size? My employer has an extremely small mailbox size limit , and it would save me a lot of time to have the current size displayed on my default mail screen rather than having to drill through a bunch of menus to eventually see how large ( in bytes ) my mailbox is.

What would really be cool is if I can just create a custom view that added a size column next to the name column in the hierarchal folder view, then I could see the size of each folder while checking email.

Any thoughts?
