Just to expand on TheAvatar's answer:

What I do, is enter a Calander Appointment (Ctrl-Shift-A); for the next followup. (essentially a "Tickler File" item).
In the bottom left corner, I enter the contact person.
If needed, I can make it a recurring appointment as you mentioned.

I get a reminder before the appointment from outlook.
Also, should I be reviewing my contacts, I can Click the Activities Tab and see all of the activities planned for a given contact (including upcoming calandar items).
By the way, in the Activities tab you can also see other contacts you've associated with this one, prior emails for this contact, Tasks you created for this contact, etc.
