Windows 7 pro using Microsoft office suite 2003. The outlook email and calendar application of that office suite worked fine for both separate logged in users of this desktop pc. After user two incorrectly entered a calendar reminder that appears blank and the recurrence symbol shows the diagonal line through the re-occurrence symbol, the bad entry could not be deleted. When that date arrived, as outlook checked for any reminders, the program immediately locked up and insisted it be closed. The user number one has no problem at all with their calendar or email using the same outlook email/calendar program. How can this "false" entry in user two's calendar be deleted without losing all other entries for future recurring or single calendar reminder events? The program itself will not allow the entry to be opened or deleted since it immediately closes when checking for reminders.
