CALENDAR - appointment will NOT delete no matter what I do! HELP!

Hi fsuadrienne,

thanks for your detailed explanation.

1. Try to delete the appointment in Outlook Safe Mode
   

   - Right-click the Start button, and click Run.

    

   - Type Outlook.exe /safe, and click OK.

    

   Tip: If Windows can't find Outlook.exe /safe, try using the full path to Outlook (for example C:\Program Files\Microsoft Office\OfficeXX, where XX is your version number).
   
   Open Outlook in safe mode - Microsoft Support

    

2. Delete the appointment from the server using Outlook Web Access (OWA).
   Delete an appointment or a meeting - Microsoft Support
   

   • To do this, log in to OWA and open the calendar.
   • Right-click the appointment and select Delete.
   • If you can delete the appointment from OWA, but not from Outlook, then the problem is likely caused by a corrupted Outlook data file. To repair your Outlook data file you can use this link: Repair Outlook Data Files (.pst and .ost) - Microsoft Support
     
     

If you are still having trouble deleting the appointment, you can use the MFCMAPI tool.

MFCMAPI is a powerful tool that can be used to manage Exchange mailboxes, including deleting appointments. However, it is important to note that MFCMAPI is a complex tool, and it should be used with caution. It is important to make sure that you have a backup of your mailbox before using MFCMAPI.

To use MFCMAPI to delete a recurring appointment, follow these steps:

1. Download and install MFCMAPI from Microsoft: Install the samples used in this section | Microsoft Learn
2. Open MFCMAPI and log in to your Exchange mailbox.
3. Expand the Root Container node and then expand the Calendar node.
4. Right-click the recurring appointment that you want to delete and select Delete.
5. In the Delete Item dialog box, select the Delete the entire series option and then click OK.
