"You have been added to a team in Microsoft Teams" info mails are not being sent when user added via Graph

[taylancelebioglu]

When guest user added to a group via MS Teams Client mails are being sent as usual before. If the user added via Graph API, information emails are not being sent for guests users anymore.

We have tried to add user either /v1.0/teams/{team-id}/members or /groups/{group-id}/members/$ref endpoint.

https://graph.microsoft.com/v1.0/teams/{team-id}/members

{
    "@odata.type": "#microsoft.graph.aadUserConversationMember",
    "roles": [
        "member"
    ],
    "user@odata.bind": "https://graph.microsoft.com/v1.0/users('<user-id>')"
}

/groups/{group-id}/members/$ref

{
  "@odata.id": "https://graph.microsoft.com/v1.0/directoryObjects/{id}"
}

Thank you for reporting this issue. This appears to be an issue or limitation with the service APIs. Unfortunately, as the Microsoft Graph SDK team, we do not have ownership of the APIs that are causing you issues. We invite you to create a question about the service API to Microsoft Q&A and tagged with one of the [microsoft-graph-*] tags, that way it will get routed to the appropriate team for them to triage:

https://aka.ms/msgraphsupport or directly https://aka.ms/askgraph

For now, we will close the issue on our side but feel free to open it in the relevant repository if you think the issue is specific to SDK. Please let us know if this helps!

Note: We will close this repository on April 19, 2024.
