Add support to get `Microsoft Teams admin center > Users > External access` details

Is your feature request related to a problem? Please describe the problem.

Dear team,

I am trying to retrieve the Microsoft Teams admin center > Users > External access > Policies and Organization settings using the Graph API. However, I have not been able to find any relevant API call in either the GA or Beta versions of the Graph API that provides these details.

Could you please confirm if this functionality is currently available, or consider adding support for retrieving Teams Admin Center external access settings via Graph API?

Please see the below image:

Thanks

Describe the solution you'd like.

I would like the Microsoft Graph API to provide endpoints that expose the External access Policies and Organization settings currently only available in the Microsoft Teams admin center (https://admin.teams.microsoft.com/ > Users > External access).

Specifically, the API should allow programmatic retrieval of:

• Global (Org-wide default) external access policy settings
• Custom external access policies (if any)
• Whether communication with unmanaged Teams accounts is enabled or disabled
• Any organization-wide overrides affecting external access

This would enable automated compliance checks, monitoring, and governance of Teams external access configurations without requiring manual navigation of the Teams admin center.

Additional context?

No response

Start by reviewing the Microsoft Teams admin center External access page and the Microsoft Graph GA and Beta API documentation linked or referenced in the issue. Determine whether endpoints exist for the listed policies and organization settings; done would mean the required external-access details can be retrieved programmatically.
