Shared channels - from the same on-demand Teams scan as the app inventory; 'external' means a tenant id other than yours.

Required Microsoft Graph permissions

Group.Read.All Organization.Read.All TeamsAppInstallation.ReadForTeam.All Channel.ReadBasic.All ChannelMember.Read.All — application permissions, granted to the app registration with admin consent.

Endpoints: GET /v1.0/groups?$filter=resourceProvisioningOptions/Any(x:x eq 'Team') · GET /v1.0/teams/{id}/installedApps?$expand=teamsApp,teamsAppDefinition · GET /v1.0/teams/{id}/channels?$filter=membershipType eq 'shared' · GET /v1.0/teams/{id}/channels/{id}/sharedWithTeams · GET /v1.0/teams/{id}/channels/{id}/members

One scan feeds both the Teams app and the shared channel reports: two to four Graph calls per team, six teams at a time. Large tenants take several minutes. Whether external people can join at all is set by cross-tenant access (B2B direct connect) - see Cross-tenant Access & B2B Trust.

If a permission is missing, this report shows a red load error with the Graph status code — not an empty table.

Shared Channels with External Members

Shared channels (Teams Connect) let people from other organisations work inside a channel without switching tenants - and without appearing as guests in your directory. Their files live in your SharePoint. Channels shared with other organisations' teams or with external people are listed first.
