Hi to all of the Outlook wizards!

I have been asked to research an add-in for Outlook 2003 SP2 / Exchange
Server that will emulate the typical "In/Out" board for employees.  Ideally,  
would have simple form where employee could click "In" or "Out" and, if going
out, select a time they will be returning.  Another form would show visually
which employees are in or out as a quick reference.

Tried searching for "out of office", but getting thousands of hits that all
seem to be related to auto reply messages.  "In office" gets me totally
unrelated items.

Does anyone know of something like this out there?

Thanks,
Bruce
