How to fix Outlook’s failure to delete Calendar events

1] Temporarily prevent the change to the calendar item from being logged
One of the first things to do here is to ensure changes to the calendar item are not logged, and right after, attempt to delete the event.
Begin by opening the Command Prompt.
You can do this by clicking on the Windows key, then type CMD in the search box.
Check the search results for Command Prompt, and be sure to open it in Admin mode.
The next step, then, is to copy and paste the following cmdlet into the Command Prompt.
Set-Mailbox <name_of_affected_mailbox> -CalendarVersionStoreDisabled $true
Hit the Enter key, then wait patiently for the database store configuration cache to expire.
Bear in mind that this will take around two hours, so go and do something constructive until the time has passed.
Finally, go and delete the Calendar event or item once the two-hour timeframe has passed on.
2] Clear the Calendar of all events and items in Outlook
The calendar function in Outlook does not have an official reset feature, but there is a way to get this done in a way that works in your favor.
- Open the Microsoft Outlook app on your Windows computer.
- From the left-hand navigation pane, please select Calendar from under My Calendars.
- Click on the View tab via the main program menu.
- Next, you must select Change View. This is located in the Current View group.
- Go to the List section to view a list of all calendar events and items from the main area.
- Click any section via the item list, the press CTRL + A. This will select all items located in the calendar list.
Finally, press the Delete button on your keyboard and right away, all events along with other items will be deleted.
In essence, then, you’ve just cleared your Outlook calendar of all events and items, which is basically resetting the tool to its default state.
3] Reset Mail & Calendar app
Repair or Reset Mail & Calendar app and see if that helps.
- Open Windows 11 Settings app.
- Go to “Apps > Apps & features.”
- The list of all installed apps will appear. Scroll down and locate the Mail and Calendar app.
- Once you find it, click on the three horizontal dots next to it and select Advanced options.
- Now, scroll down and click Repair or Reset.
4] Use the Outlook web app
If you’re finding it too difficult to use the desktop version of the Outlook app to remove calendar events, then we suggest simply using the Outlook web app to delete the problematic event or item. In most situations, the web app is not affected by issues plaguing the desktop version, and the same goes for the mobile app as well.
