I would like to have one of Outlook's reminders appear. Then, when I
acknowlege it, I would like Outlook to, in effect, 'count down' until
a certain period of time has elapsed, then pop up another reminder.

In short, rather than a reminder that occurs at a specific time of
day, I'd like a recurring reminder that only appears when a certain
amount of time has elapsed after I manually acknowlege the last
reminder.

Is there an easy way to set up such a thing in Outlook?

Won't the snooze option work for you?
