Delete all calendar appointments for a list of users using powershell

[muhamedrafeeq]

Hi,

Because of scheduling remote learning classes, the teachers has got numerous calendar events in their Teams calendar and its crashing the Teams app. Can somebody please help me with a powershell script to clear the calendar events for a list of users using input file (csv or txt).

@muhamedrafeeq  This shouldn't happen. File a support incident with Microsoft to have them investigate why the calendar is causing a problem.

Hi guys,

I really need to remove the calendar events for many staffs (o365 mailbox). Can somebody share a powershell script to do the same ?

@muhamedrafeeq have you tried using the Remove-CalendarEvents script ?

Hi @Ardamilola ,

Yes I tried the Remove-CalendarEvents script, but I believe that script is for future meetings and I want to clear the past meeting entries too. Also I got to clear calendar events for around 1000+ users. So a script which calls the input list would be feasible.

Hi @muhamedrafeeq and @Ardamilola, 

Did you solve this problem? 

I'm facing the exactly problem here. 

I tried 

Remove-CalendarEvents -Identity user@domain.com.br -CancelOrganizedMeetings -Confirm:$false -verbose

and

Get-Mailbox -ResultSize Unlimited | Search-Mailbox -SearchQuery "kind:meetings AND From:user@domain.com.br" -DeleteContent

But no success :(

The problem with Remove-CalendarEvents is that it's forward looking and I suspect that you want to remove events in the past. This can be done with the Search-Mailbox cmdlet using a command something like this:

Search-Mailbox -Identity MailboxtoSearch -SearchQuery 'Received:01-Jan-2019..15-Dec-2020 kind:meetings' -TargetFolder Searches -TargetMailbox AnotherMailbox -LogOnly -LogLevel Full

This command looks for calendar meeting events in a certain date range and creates a report in the target folder in the target mailbox. If you want to delete the items, run: 

Search-Mailbox -Identity MailboxtoSearch -SearchQuery 'Received:01-Jan-2019..15-Dec-2020 kind:meetings' -DeleteContent

Thank you @Tony Redmond  !

I issued this command

search-Mailbox -Identity user@domain.com.br -SearchQuery "kind:meetings" -DeleteContent -confirm:$false -Force

and Worked ! thank you for your time ! 

also I used -confirm:$false -Force because i needed to run in many users. 

Thanks Again ! Best Regards !
