In this blog post I will show how to disable the automatic creation of an online meeting in Outlook. The default behavior is the following: When a user creates a meeting, then an online meeting is automatically created via Teams. This can be changed in Outlook by the user himself. But it can also be changed centrally. I will show this now.

Let’s say we have a mailbox with the email address f.bizeps@sid-500.com. This mailbox should be changed so that no automatic online meetings are created, but “normal” Outlook meetings.

All we need is PowerShell.

Open PowerShell,ISE or VS Code.

Make sure the Exchange Online Management Module is installed. If not, enter the line below and hit enter.

Install-Module ExchangeOnlineManagement -Force -AllowClobber

Now, connect to Exchange Online.

Connect-ExchangeOnline

Next, we disable the User Mailbox setting “OnlineMeetingsByDefaultEnabled”.

Set-MailboxCalendarConfiguration -Identity f.bizeps@sid-500.com -OnlineMeetingsByDefaultEnabled $false

Finally, of course, we review what we have done.

Get-MailboxCalendarConfiguration -Identity f.bizeps@sid-500.com | Select-Object *OnlineMeetings*

Amazing!
