Unfortunately, code can only interact with rules in Outlook 2007. For
Outlook 2003, you'd have to transform all the rule actions into VBA code.
If you want code to run at a certain time, then create named Tasks or
recurring Appointments with reminders you can check using the
Application_Reminder event (or Reminders.ReminderFire). If you need these
operations to occur when Outlook isn't running, then you need to look at
using Redemption (http://www.redemption.com) if you want to design an
application that runs as a Windows Service or an .exe that's fired by a
Scheduled Task.

Dear Eric,
Thank you for your speedy, well-rounded and valuable response. I appreciate
it very much.
Being somewhat of a novice and under time pressure right now it may take me
a while to digest fully and to implement. Nonetheless I shall give you
further feedback in the fullness of time.
Best regards.
