How to Prevent Outlook / Microsoft 365 from Automatically Adding a Teams Meeting

Microsoft 365 automatically adds a Teams meeting by default, but your organization may prefer to use Zoom and Slack.

As an individual user, you can disable automatically adding Teams meetings in the following places:

• Microsoft 365 Online Calendar
• Outlook Mac Desktop Client
• For Microsoft 365 Organization Admins (PowerShell)

Microsoft 365 Online Calendar

1. Go to https://outlook.office.com/mail/
2. Click the Gear at the top right to go to settings
3. Click “View all Outlook Settings” at the bottom
4. Once settings are open, click on “Calendar” on the left and then uncheck “Add online meeting to all meetings”
5. Teams meetings should no longer automatically be added to Outlook Calendar Meetings

Outlook Mac Desktop Client

1. Open the Mac Outlook desktop client
2. In the Mac menu at the top, click “Outlook” > “Preferences”
3. Click “Calendar”
4. Uncheck “Add online meeting to all meetings (Applies to Microsoft 365 accounts only)”

You should no longer have Teams meetings automatically added when creating a meeting through Microsoft 365 (M365) or Outlook.

For Microsoft 365 Organization Admins (PowerShell)

You can disable this feature at the organization level with the following PowerShell command:

Set-OrganizationConfig -OnlineMeetingsByDefaultEnabled $False
