Removing Exchange Online calendar events when the meeting organizer leaves

“Hey, look! A new Office 365 feature!”

I get to say this a lot given how often Microsoft drops new features into various parts of the service. Sometimes they announce these features in advance, and sometimes they don’t. Sometimes these features are large, and sometimes they’re small.. but even the small ones are often surprisingly valuable.

Today’s example: the new Remove-CalendarEvents cmdlet, which solves the issue of what to do with recurring meetings when a user leaves or is on extended leave. Here’s what the documentation says:

This cmdlet cancels meetings in the specified mailbox where the mailbox is the meeting organizer, and the meeting has one or more attendees or resources. It doesn’t cancel appointments or meetings without attendees or resources.

This is perfect for handling the case when someone leaves an organization and leaves behind recurring meetings, but it’s also useful for cleaning up calendar items for people who are on parental leave, medical leave, or other types of absence with a defined start and end time.

You can cancel all meetings with the -CancelOrganizedMeetings switch, or you can specify a date range with switches to specify the start date and the number of days or the end date to cancel. Keep in mind that if you don’t include -CancelOrganizedMeetings, nothing will happen when you run the cmdlet– if you want to see what it would do, you can use -PreviewOnly. I am not sure why the team didn’t use the standard -WhatIf switch, but that’s a minor point.

The cmdlet is very easy to use. I wanted to cancel all future meetings organized by a user who’s left my tenant, so this is what I did:

A single cmdlet will remove all of the target user’s meetings

Note what happened on the first try– I didn’t specify any switches, and the cmdlet warned me that it wouldn’t do anything… and indeed, it didn’t. The second attempt did exactly what it was supposed to:

Poof! no more meeting

I was delighted to see this result– it’s proof that Microsoft is paying attention to the small sharp edges that sometimes annoy administrators disproportionately. Hats off to the calendaring team (hi, Julia!) and thanks for listening.
