When trying to get the members of a private channel we get:

GET /chats/{id}/members

https://graph.microsoft.com/v1.0/chats/XXXXXX@thread.skype/members

{
"error": {
"code": "BadRequest",
"message": "Resource not found for the segment 'members'.",
"innerError": {
"date": "2020-09-25T04:17:33",
"request-id": "b250340f-2ce0-45a8-b2d1-cd23ab4b5bcb",
"client-request-id": "235f0d9d-0c84-5c5a-30ff-144adc25d8e7"
}
}
}

This works in the beta version but not in V1

It would be useful if the chatMessage resource could return the total number of hostedContents when listing team channel messages by using the following methods:

1. GET /teams/{id}/channels/{id}/messages


2. GET /teams/{id}/channels/{id}/messages/delta

As a third-party security service provider, we need to scan all the messages in chats and send warning messages to inform users when found a phishing URL or malware were sent in chats.

So we need to send messages in a chat by using Application permission since Delegated permission requires that the delegated user is one of the members of that chat.

We wish can use an App to send messages to every existed, or newly created chats in Teams.

Currently the API 'Send chatMessage in a chat' not supports Application way.

I want the feature to get a list of chats with application permission. For developing a custom application for the eDiscovery/litigation purpose, administrator need application permission to get a list of chats.

After I create a private channel with Graph Beta I had to manually click on the Files tab for the Team clients to create the SharePoint site. I would like to Graph Create Channel API to create the underlying SharePoint site as well.

Users who posted message in Teams Channel can edit the messages later but through the graph api there is no options to update messages or delete messages.
POST /teams/{id}/channels/{id}/messages/{id}/replies seems like we can reply to the message but not update the previous message sent. Here I am talking about the same user's credentials. In Teams, a user can edit but not using graph api

It would be useful to have Graph access to the telephony objects in Teams. Right now, I need to use an azure runbook that runs new-csonlinesession in order to retrieve Teams telephony objects like users, phone numbers, call queues, auto attendants, etc.

Currently, the only way to send messages is to post a message on a channel in a team. It would be great if there could be an API to send a direct message to the users. Please let me know if it already exists, because I could not find any such method in the chat object here :
https://docs.microsoft.com/en-us/graph/api/resources/teams-api-overview?view=graph-rest-beta

Please support getting MIME of a chat message just like we do for Mail Message.

Do not deprecate Application Permissions ability to generate Teams Meetings. This is a valuable function that is used to quickly generate a collaborative meeting for our IT teams to discuss major incidents or outages. Current delegated permissions flows do not allow us to do this in the same manner and will lead to us losing this functionality

We can assign users to shifts through Graph, but we can't assign users to Shifts Groups.
It is essential for us as an organization, that we can assign users to groups in a Shift. We can add them to the TEAM, but from there, they can't take shifts in the groups.

We can get assigned Shifts through Graph (and Power Automate / Flow). But we can't get open shifts. It is essential for us as an organization, that we can run through open shifts and offering them to users.

We need to get the most recent (MS Teams) chats for a user and need to order by lastUpdatedDateTime (or at least createdDateTime). Please allow this.

The error when using $orderBy for the me/chats endpoint currently is:

"Query option 'OrderBy' is not allowed. To allow it, set the 'AllowedQueryOptions' property on EnableQueryAttribute or QueryValidationSettings."

We currently have a webhook to receive notifications of new callrecords from Teams. In cases where we missed notifications, or in cases where we need to go back in time, it would be useful to have the ability to query callids based on date and time. For example, get all IDs between datetime and previous datetime.

With the announcement at Ignite 2019 of Pinned Channels it would be great if we could get access to them via the Graph API. You could add a property to the Channel called 'isPinned' and/or make a call to get all pinned channels in one hit e.g. me/pinnedChannels

According to https://docs.microsoft.com/en-us/graph/api/resources/teamsapp?view=graph-rest-beta, only delegated permission is supported to manipulate Teams AppCatalog which means a sign-in user is needed when taking use of those APIs. However, the Application permission can provide the ability to make related actions more automatically and support more meaningful and realistic use-cases.

For example, my use-case is to provided an application to automatically install a new Bot, created in Azure, to Teams. So I really think the Application permission is needed.

In the current graph beta, user chats and their messages can be enumerated using GET /users/{id}/chats and GET /users/{id}/chats/{id}/messages. However, new messages cannot be posted to the messages endpoint i.e POST /users/{id}/chats/{id}/messages . Please add this functionality.

The desired functionality exists for team channel messages by posting to the channel messages endpoint (POST /teams/{id}/channels/{id}/messages). Replicating this for user chats using the same json payload would seem to be the most appropriate solution.
