Copy them so they break out of the recurrence and change the category of the

Excel or make recurring in outlook, export to excel then import to convert

Export here, import back again? SO not an elegant solution!

I commented as much on another thread on the same basic topic:

"In Outlook 2003, you could set up a recurring calendar item - obviously
saves time over setting up individual calendar events - and tag the series
with a colored-coded category. THEN, you could open up each instance of a
recurrence and change the category color.

Sounds rather idiosyncratic but... I relied heavily on this functionality in
my small business. I'd set up A-B-C-D series with a color like 'important'.
Date A would arrive and I'd know I needed to follow up with Person 1. Once
that communication was satisfied, I could change the category color to 'none'
which told me that the matter was resolved. Date B would arrive, and I'd
repeat the process.

It was one of the many little ways I used Outlook's calendar function as a
running to-do list (more than Tasks, I must admit).

Now I see Outlook 2007 has consolidated the category functions across
Calendar, Contacts, Tasks, etc, dramatically expanding the category choices -
which is great. So, with one hand they giveth and with the other they taketh
away. Not cool. I want a patch!"
