List Microsoft 365 capabilities for default policy

Namespace: microsoft.graph

Get a list of Microsoft 365 cross-tenant capabilities configured for the default cross-tenant access policy. The returned collection is a heterogeneous collection of derived types of m365CapabilityBase, differentiated by their @odata.type property.

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type	Least privileged permissions	Higher privileged permissions
Delegated (work or school account)	Policy.Read.All	Policy.ReadWrite.CrossTenantCapability
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	Policy.Read.All	Policy.ReadWrite.CrossTenantCapability

Important

For delegated access using work or school accounts where the signed-in user is acting on another user, they must be assigned a supported Microsoft Entra role or a custom role that grants the permissions required for this operation. Managing Microsoft 365 cross-tenant capabilities affects the entire cross-tenant access policy, so no lower-privileged built-in role covers all capabilities. This operation supports the following built-in roles:

• Global Administrator - required for all capabilities, because managing the cross-tenant access policy requires directory-wide privileges.
• Exchange Administrator - supported only for the MailTips, Calendar Sharing, and Free/Busy capabilities.
