    Hi Shwe Sin,

    Thanks for reaching out!

    It is an expected behavior, when the user ID is provided.

    As you are using Graph Explorer delegated permissions, you can get the results for the logged in user only.

    But using Application permissions, we can get chats of the specified user (who may not be signed in or is different from the signed-in user) in the organization.

    Note: APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

    Hope this helps.

    Hi @Shwe Sin

    The /users/{user-id} endpoint is usually only supported in application context, you can try calling that in postman. Before that, you need to grant the TeamsAppInstallation.ReadForUser.All application permission to your app, and then use the Client Credentials flow to get a token.

    Let me know if you have any further questions, feel free to post back.

    Hi @Shwe Sin

    I noticed that the API documentation for that endpoint was updated yesterday and I'm not sure if there are any changes to the permissions or features that apply to that endpoint.

    For this, I recommend you raise a support case with Microsoft Graph, a Support Engineer will be able to assist you better. You can raise support ticket from: or
