The behavior is controlled by the “Add online meeting to all meetings” / “Make every meeting online” setting, which exists both in Outlook clients and (optionally) at the organization level via PowerShell. Even if it is turned off in Outlook on the web, it can be re‑enabled or overridden by other Outlook clients or by an admin‑configured default.
To stop Teams links from being added again, all relevant places must be checked:
- Turn it off in every Outlook client used
The setting exists in all Outlook clients (Windows, Mac, web, Android, iOS). If any client has it turned on, that client will keep adding online meetings when used.- In each Outlook client, open Options/Settings → Calendar → Online meetings (or similar) and turn off Add online meeting to all meetings / Make every meeting online.
- Check for organization‑level defaults (admin)
Admins can set a default that makes all meetings online using Exchange Online PowerShell:- The parameter
OnlineMeetingsByDefaultEnabledonSet-OrganizationConfigcontrols whether meetings are online by default. - If a user has never changed the setting in a supported Outlook client, the org default applies. Once the user has toggled it, the client setting takes precedence and the org default is ignored.
- If the setting keeps reverting, an admin should verify that:
-
OnlineMeetingsByDefaultEnabledis not being repeatedly enforced by scripts or configuration baselines.
-
- The parameter
- Ensure the mailbox setting is not being reset for the user
Admins can set defaults that apply to new users or users who have not modified the setting. If scripts or policies recreate/reset the mailbox or profile, the default may be re‑applied and the user must toggle it off again in Outlook. - Confirm the correct account is being edited
If multiple accounts are configured in Outlook on the web, ensure the Add online meeting to all meetings setting is turned off for the specific business account used for bookings.
Once the setting is turned off in all Outlook clients for that account and no admin script is re‑enabling it via OnlineMeetingsByDefaultEnabled, new bookings should stop automatically adding Teams meeting links.
