You can't remove a calendar item or an email message in Outlook in Office 365

PROBLEM
You can't remove a calendar item such as a meeting request, a reminder, or an email message in Microsoft Outlook in Microsoft Office 365. Additionally, if you try to remove a meeting request, you may receive an error message that resembles the following message:

This meeting cannot be removed because you are the meeting organizer.
SOLUTION
To fix this problem, use one or more of the following methods. Try Method 1 first. If that doesn't fix the problem, try the next method.

Recommended method

Method 1: Use the Search-Mailbox cmdlet

Use the Search-Mailbox cmdlet to search for and remove the item. For more information, see Search and delete messages.

Additional methods

Method 2: Use Outlook Web App

Try to delete the item in Outlook Web App. If you can't delete it in Outlook Web App, go to the next method.

Note If you can't complete a task in Outlook but you can complete it in Outlook Web App, this might mean that Outlook has to be updated.

Method 3: Run Outlook commands

Depending on the kind of item that you're trying to remove, you can use the following command line switches to remove the item.

Caution Exit Outlook before you run any of these switches.

  • Click Start, enter outlook /cleanreminders in the search box, and then press Enter.

    Note The /cleanfreebusy and the /cleanprofile switches aren't available in Outlook 2013.
After you run the applicable switches, start Outlook, and then try to delete the message again.

Method 4: Delete the message after you edit it

  1. In Outlook, double-click the email message.
  2. In the Move group in the message ribbon, click Actions, and then click Edit Message.
  3. Remove some characters from the message, or add characters to it.
  4. Click File, and then save the message.
