I used the Easy Transfer wizard to move my XP installation, including Office
2003, to a new Vista box. All seems to be well in Outlook, except that trying
to open any recurring appointment gives an error "Object is not valid."
This happens both with pre-existing appoinments and new ones I create in
Vista. Non-recurring appointments give no problems.

Can't change recurring to non-recurring because I can't open them.

Help?
