Question details

The user needs a way to configure newly created Microsoft Teams groups to automatically generate connected SharePoint sites with more restrictive default sharing permissions.

How to Create a More Restricted SharePoint Site for a Teams Group

Product: SharePoint Online, Microsoft Teams
Device & OS: not provided
Scenario: Administrators want to implement stricter default data sharing policies for the backend SharePoint sites that get automatically provisioned whenever a new team is created in Microsoft Teams.
Observed behavior: SharePoint Online currently does not provide a native, out-of-the-box setting to adjust or restrict the default sharing level specifically for sites created via Microsoft Teams provisioning.

Before you start

Ensure you have SharePoint Administrator or Global Administrator privileges in your Microsoft 365 tenant to manually adjust sharing configurations and implement Power Automate solutions.

Solution 1Recommended

Automate Permission Restrictions via Power Automate

Since there is no built-in UI toggle, using Microsoft Power Automate is the recommended workaround to automatically adjust permissions when a new Teams group is created.

By utilizing Power Automate, administrators can intercept the site provisioning process and apply stricter sharing defaults using the SharePoint REST API without manual intervention.

Create a new Cloud Flow

Log into Power Automate and create an automated cloud flow triggered by the creation of a new Microsoft Teams group or Microsoft 365 Group.

Configure the HTTP Request Action

Add a 'Send an HTTP request to SharePoint' action to modify the newly provisioned site's default sharing settings via the SharePoint REST API.

Test the provisioning workflow

Save the flow and test it by creating a new Teams group. Verify in the SharePoint Admin Center that the newly connected site reflects the restricted external sharing permissions.

Automate Permission Restrictions via Power Automate

Community Support: For detailed API endpoints, flow templates, and advanced custom guidance, it is highly recommended to consult the Microsoft Power Automate Community.

Solution 2

Manually Update Site Permissions After Creation

Administrators can manually restrict sharing settings for individual sites immediately after a new Teams group is provisioned by users.

Frequently Asked Questions

Can I globally disable external sharing for all new Teams-connected SharePoint sites?

Yes, you can set the tenant-wide external sharing setting in the SharePoint Admin Center to 'Only people in your organization'. However, this will enforce the restriction on all current and newly created sites, rather than allowing granular control purely based on Teams creation.

Why do Microsoft Teams create SharePoint sites automatically?

Every team in Microsoft Teams requires a reliable backend storage solution to manage uploaded files, wikis, and document libraries. SharePoint Online automatically serves as this robust document management backend to handle permissions, versioning, and storage.

Where can I request Microsoft to add a default sharing setting for Teams sites?

You can submit feature requests, share feedback, or upvote existing suggestions on the official Microsoft Feedback Portal for SharePoint under the site management and administration category.
