Until now to get Microsoft Teams messages I check the subject field to see if it contains "IM" as described in the documentation:
GET messages returns chats in Microsoft Teams
In both the v1 and beta endpoints, the response of GET /users/id/messages includes the user's Microsoft Teams chats that occurred outside the scope of a team or channel. These chat messages have "IM" as their subject.
For the past few days, that "IM" is no longer showing up in the subject of the message, so now we have no information to determine if it's a Teams chat.
The "known issue" was that /messages was returning these messages. It sounds like they rolled out a fix for this issue. Since this was considered a bug, the current state is how it was designed to work - /messages was intended to only return email messages.
This is why it's not a good idea to pull a dependency on a known issue; when they fix the issue, it breaks your code. At the moment there doesn't seem to be a mechanism to retrieve these messages but, based on this PR in the documentation, it looks like it will be coming soon.

I am trying to use Microsoft.Graph to send add a message to a chat. I have successfully found my team and created a channel for the messages to go into but when I try to actually send the message, I get a Forbidden error message. This is covered by the ticket:
Microsoft Graph API for Teams: Send Channel/ Chat messages and I am getting the same problem that #Koelier originaly got.
The reason that this is not fixed is that following the answer does not fix my problem. Indeed, the ChannelMessage.ReadWrite.All does not appear in my list. I am looking for the app to run as a service, in the background so the Application Permissions is the method I need to use.
I note that I am not alone in this as #johnnycardy notes that he has had exactly the same problem as me. Furthermore, I linked to the document referenced by #nastassiar and it did not reference the ChannelMessage.ReadWrite.All at all. I can assume it did once but not anymore.
Any guidance would be gratefully received.
Just checked the permissions to perform the same using graph explorer and the below are the ones that I had to add.
ChannelMessage.Send - Allows the app to send channel messages in Microsoft Teams, on your behalf.
Chat.ReadWrite - Allows an app to read and write your 1 on 1 or group chat messages in Microsoft Teams, on your behalf.
ChatMessage.Send - Allows an app to send one-to-one and group chat messages in Microsoft Teams, on your behalf.
Group.ReadWrite.All - Allows the app to create groups and read all group properties and memberships on your behalf. Additionally allows the app to manage your groups and to update group content for groups you are a member of.

I'm calling https://graph.microsoft.com/v1.0/users/{user_id}/messages/ to paginate through all user messages. I'm using app permissions for access, which works fine.
But I'm getting more messages than expected, and I'm not sure why. Is it possible the /messages endpoint includes messages from shared mailboxes available to user_id, too?
If so, what is the way to suppress that? Thanks.
What gives you the impression that you are getting more messages than is expected? Note that /messages returns all of the messages in the mailbox across all of the folders.
The documentation states that shared message access is performed with delegated permissions. You shouldn't be seeing shared messages when using application permissions. Does your application use the Mail.Read.Shared or Mail.ReadWrite.Shared scopes? If so, you should be able to remove them and I'd expect it shouldn't have access.
From Microsoft's Known Issues page:
GET messages returns chats in Microsoft Teams
In both the v1 and beta endpoints, the response of GET /users/id/messages includes the user's Microsoft Teams chats that occurred outside the scope of a team or channel. These chat messages have "IM" as their subject.
So the solution is to ignore all messages with subject == "IM".
I have a logic app which posts a channel chat message to teams automatically when a new item is created in SharePoint. This I have working but our client requires that all the team members receive a banner alert and activity feed which I am having a lot of difficulty with.
What I've already tried...
Using a Incoming web hook on the teams channel - this was a very simple way to post from the logic app but the incoming webhook don't seem to support mentions.
Using the msft graph api - The /team/channel/message endpoint can post messages and user mentions but the this endpoint doesnt support channel or team mentions. It also appears that the graph API needs to use delegated permissions to post messages in teams. I'm using application permissions as this is a logic app. The logic app HTTP post connector doesnt offer the "connect as username#tenant.com" some of the other connectors use.
Using the flowbot post message - Like the above channel and team mentions are supported here so the post is added to the channel but with no notification to the team members
Using a notification only bot - I thought I nearly had it with this one. Microsoft's node bot sample number 57 looked like it can do most of what I want, it iterates through the users in the team and messages them this a customisable alert message...
https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/javascript_nodejs/57.teams-conversation-bot
However I can't see how this bot can be triggered from my logic app as it seems to require an existing conversation context or an #mention from within teams to start communicating with users.
What I'm considering trying next
Iterating users within the logic app - Next I plan to try and get team membership from the graph API and iterate the members in the Logic App, posting a message to each user separately. I had hoped to utilise the group #mention feature as a simpler way so I'd be grateful if anyone had any thoughts on other ways of doing this, or maybe there's something wrong with what I've already tried that you could give me some expertise on.
Thanks in advance ;)

You're on the right track with the Bot, but you're wanting to send something called a "Pro-active" message. You need the bot registered in the channel in order to get access to a few key properties (conversation id, service url, etc.), but you can use those to send a message from -outside- your bot (e.g. in an Azure Function). You might be able to do this directly from a Logic App, but I haven't tested that specifically.
To find out more, see my answer at Programmatically sending a message to a bot in Microsoft Teams but I've also got a recent blog post that you might find interesting for background on this at How Bots Actually Work.
Hope that helps
You can use Graph to post a message in 1:1 chat as long as you have the chat it. You can find the answer in this post Send message to personal Chat via Graph API
You can also call Graph API from Logic Apps. (https://techcommunity.microsoft.com/t5/integrations-on-azure-blog/calling-graph-api-from-azure-logic-apps-using-delegated/ba-p/1997666#:~:text=Calling%20Graph%20API%20from%20Azure%20Logic%20Apps%20using,Manage%20-%3E%20Certificates%20%26%20secrets%20More%20items...%20)
I'm going over the Microsoft Teams section of the Graph API and trying to find out how to do two things:
Create a new chat, giving it a topic that correlates to an entity in our app (essentially creating a chat around an entity), invite specific users into it, and send messages to the chat.
Access the currently logged-in user's private chats, filtered by their topic, and show their contents inside our app.
For #2, it looks like it should be possible using beta endpoint of the Graph API, but I get 403 Forbidden errors both in the Graph Explorer when trying to access https://graph.microsoft.com/beta/me/chats, and in my own app, after enabling the Chat.Read permissons for it.
For #1, it looks like the API doesn't officially support creating new chats at all.
Is there any approach we can use to create and manage chats? Is there an alternative, perhaps not MicrosoftGraph-based API?
as you mention, the ms graph doesn't yet support initiating group chat. You would use the MS Bot Framework for this: https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/bots/bot-conversations/bots-conv-proactive
I see the docs on these Chat api do exist, but they are not present in the Graph Explorer. I tired testing them in the OfficeApiEditor tool with a v2.0 App Registration and Delegated permissions (Chat.Read) and i get this:
Failure - Status Code 500
"code": "InternalServerError",
"message": "Error while processing response.",
so maybe it will take some time before they are really available in beta.
In MS teams, there is a api called ChatMessage to post a message to a chat(only if the chat already exist or started). But, there is no api to create/start a new chat. I have raised a feature request. Do vote for this to suggest this idea to Microsoft.

I am looking at Teams Channel Create Chat Message method (currently only available in beta).
We have an application which manages groups of users and would like to integrate with MS Teams - create a Team, add Channels and send messages to the channel - all without a user. For this I have followed "Get access without a user".
However I notice that for this and other message level functions (list messages) Application permission is "Not Supported" and for our use case Delegated permissions is not really an option (similar to this).
Does anyone know why these are only available for Delegated Permission? is there a plan to enable this or is will this always not be "Not supported" for Application Access?
I appreciate that giving an Application full access to all messages may be something that Admins would not be keen on, but being able to post and retrieve messages from channels the application has created seems (to me) to be reasonable (perhaps the permissions model isn't that fine grained yet).
This is possibly an overlap of Unable to “List channel messages” on Azure AD Graph API Beta - the OPs answer contains an unanswered similar question.
We aren't currently sharing road map externally of when these types of things are being updated.
What we do ask is that you request these on our UserVoice channel so that we can track the demand and prioritize accordingly. If you can go here and add this request I'd appreciate this and I'll let the PM who owns this know https://developer.microsoft.com/en-us/graph/support
