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?

Thanks for any answers or suggestions.
