When you get the illegal operation, is there a button that says "Details"? If so, click on that and tell us what it says When I do a search on " outlook illegal operation recurring appointment" everything I see says to reinstall Outlook 98 right over top of itself..have you tried that? No need to uninstall Outlook and lose stuff, just reinstall it right over top of itself. Good luck, Linda F.

I am able to access the "recurrence" window but as soon as I try to change the date for the activity, I get the message. It will allow me to totally delete the activity or add a new activity. My inclination is to just deal with it assuming that I'd have to re-install Outlook to fix this but I thought I'd ask this most experienced and learned group for advice first.
