Fix Microsoft Teams Site Automatically Changing from Public to Private

Product: Microsoft Teams
Device & OS: not provided
Scenario: Managing Microsoft Teams site visibility and group settings.
Observed behavior: The team site automatically changes from public to private, even after being manually set back to public.

Before you start

Ensure you have the necessary administrator permissions in Microsoft 365 to review audit logs, Power Automate flows, and Microsoft Graph API applications.

Solution 1Recommended

Check and Disable Power Automate Flows Modifying Group Visibility

Identify automated flows or scripts using the Microsoft Graph API that are resetting the team's visibility to private.

Often, this issue is caused by a user who has created a workflow that automatically changes the group type through the Microsoft Graph API. A PATCH request sent to the group update endpoint can easily overwrite your manual visibility settings.

Determine the scope of the issue

Check whether this visibility change affects all existing team sites or if it also occurs right after you create a brand-new team site.

Review automated scripts and apps

Look into any Power Automate flows, scripts, or third-party applications in your environment that have permission to update Microsoft 365 groups.

Search for specific Graph API requests

Check for HTTP requests targeting 'https://graph.microsoft.com/v1.0/groups/{id}' with a PATCH method where the JSON body includes '"visibility": "Private"'.

Temporarily disable suspected automation

Once you locate a workflow making these changes, turn it off temporarily. Monitor the Microsoft Teams site to confirm whether it successfully remains public.

Review Audit Logs: If you cannot find the flow causing the issue, review the Microsoft 365 audit logs to see exactly which user account or application is triggering the privacy change.

Frequently Asked Questions

Why does my Microsoft Teams site keep reverting to private?

This usually happens when a background automated process, such as a Power Automate flow, a script, or an application using the Microsoft Graph API, is configured to periodically update the Microsoft 365 group visibility back to 'Private'.

How can I find which app is changing my Teams visibility?

You can check the Microsoft 365 audit logs in the compliance center. Search for group update events on the affected team to identify the specific user, service account, or application ID that is making the changes.

Can a Power Automate flow change team settings without my knowledge?

Yes, if a Power Automate flow was set up previously (perhaps by another admin or user) with an HTTP request action utilizing the Microsoft Graph API, it can patch a group and modify settings like visibility, mail enablement, and group types automatically in the background.
