That’s it, we hope one of these methods helped you to delete unwanted Calendar events on iOS. To sync your iPhone Calendar app with Microsoft Office 365, make sure your iPhone has access to the Internet, and then launch the Settings app, select Mail. To do this, select the respective calendar event, choose Report Junk, and then select Delete and Report Junk. If the calendar event you’re trying to delete was sent by an unknown sender, you can simply flag it as junk and then remove it using your Mac. Removing the sender’s email account from your iOS device and adding it again should automatically remove all those stubborn iPhone Calendar events connected to the respective email address. If the Calendar is not visible on the left, select View → Show Calendar List. If the Calendar event you’re trying to delete was created by someone else, you can unsubscribe from the calendar. You can now delete the entire ‘Remove events’ calendar from your phone.Now, open the event you want to delete and then move it to your new ‘Remove events’ calendar.Create a new Calendar on your iOS device.Keep in mind that this method will delete the entire calendar, so use it only if you’re OK with that. Then, go back to the first calendar, tap the Information button (the red i button) and the Delete calendar option should now be available. 1: Open icloud in Web Browser click on Calendar in left pane click on sharing icon, then click on Public Calendar and then Copy link, then OK 2: Now open calendars in outlook, Click on Add Calendar or Open Calendar in above control pane and then click on From Internet, paste the copied link there and proceed. If the Delete option is not visible, create a new calendar. You can use this method to disable event syncing with any third-party calendar tools. Then, enable iCloud sharing and the problematic event should be gone now. Type AllowUnregisteredMapiServices for the name of the DWORD, and then press Enter. On the Edit menu, point to New, and then click DWORD Value. Locate and then click the following subkey in the registry: HKCU\Software\Microsoft\Office\12.0\Outlook\Security\. This should delete all the calendar data and events from your iPhone. Click Start, click Run, type regedit in the Open box, and then click OK. Turn off iCloud sharing for all your calendars.


This often happens with recurring events imported from Outlook.
