The information in this article applies to:
When you try to view or delete a recurring appointment in Microsoft Outlook 97, Day/Week/Month view, you may get the following error message:
   Can't open this item. The object could not be found.
To resolve this problem, do the following:
1. On the View menu, point to Current View and click Recurring
   Appointments.
2. Double-click to open the appointment or right-click then click Delete
   to remove the appointment.
NOTE: If you are opening an item in step 2 above, this workaround will only
let you open the recurring series and not the individual occurrence.
