Get 403 forbidden to list private channel messages

problem asker 61 Reputation points

I login graph explorer with admin user to try list teams channel messages{team-id}/channels/{channel-id}/messages

but when I list a private channel (admin user is not member) or private teams (admin user is not member) messages will get 403 Forbidden.

Is only member can list private team or private channel messages?
There has any solution for admin user to list private team or private channel messages? (admin not member, and I don't want admin user become those teams/channels member)

    Hi @problem asker ,

    Any team owner or team member can create a private channel but only members of that private channel can list the messages. Team owners can not see the files, conversations or the member list of a private channel. You can check this documentation to know more.

    Alternatively, you can use application permissions but that fall under Protected APIs.

    Before calling this API with application permissions, you must request access. For details, see Protected APIs in Microsoft Teams.

    Hi @problem asker

    This is an expected error, only the owner or member of a private channel can list private channel messages, and as far as I know there is currently no support for listing private channel messages using application permissions. I suggest you submit user voice seek support from the Microsoft Graph product team.
