No, that's not possible to do with a custom form. An Outlook 2007 add-in probably could do it, though.

Hi all.

I have made a custom form that a user can create appointments from. These
appointments are visible in the main outlook calendar, but they can also be
deleted there.

I want the user to delete appointments from my form and not in the outlook
calendar.

Is it possible to lock an appointment in the main outlook calendar so they
cannot be deleted.
And if it is possible, how?
