How to delete an Outlook Calendar item that causes Outlook to crash

We had a customer who was trying to delete an Outlook calendar entry, but it wouldn't delete no matter what we tried or who tried to delete it.  We used the following steps to delete it:

1. Download the MFCMAPI tool.
2. Run the downloaded too
3. Go to Session->Logon and Display Store Table
4. Select your profile
5. Select Mailbox
6. Expand "Root Container"
7. Right click "Reminders" and select "Open Contents Table"
8. New Window Launches with Title Reminders
9. Select all the reminder items listed there, Right click and select "Delete Message"
10. Close MFCMAPI

Reopen Outlook and see if the problem entry is gone.
