Add Teams Chat Member API call inexplicably Failing
I have tried every possible permutation of this API call that I can imagine. Nothing works. I already started a thread on this, but now it appears to be glitched and I can no longer reply to message sin that thread for some reason. What can I do to contact Microsoft Support and speak directly to their API team? The responses I have gotten all appear to be AI generated and NONE ARE CORRECT. I really need help, from a human, that actually might understand what's going on here. Please help. "#microsoft.graph.aadUserConversationMember' for 'odata.type' is not valid for this operation." <- I am receiving this error despite the fact that we already have several users in this channel with that same type. This API call is intended to invite a user to an existing group chat. This should really be a very simple thing. 1. ALL users in the group chat already have type = '#microsoft.graph.aadUserConversationMember' so the error message doesn't even make sense. 2. This IS a Group chat. NOT a channel. NOT a one on one chat. 3. The Inviter has permission to invite users to this groupchat through the frontend. (and in fact can do so using the frontend.) Why is this API call failing? I have tried scrubbing the API call of special characters, I have tried using the beta endpoint, I have tried several different formats for the input. ERROR: {"error":{"code":"BadRequest","message":"The provided '#microsoft.graph.aadUserConversationMember' for 'odata.type' is not valid for this operation.","innerError":{"date":"2026-02-10T19:11:28","request-id":"XXXXX","client-request-id":"XXXXXX"}}} POST URL: https://graph.microsoft.com/v1.0/chats/IDHERE/members BODY: { "chatType": "group", "\u0040odata.type": "#microsoft.graph.aadUserConversationMember", "user\u0040odata.bind": "https://graph.microsoft.com/v1.0/users/IDHERE", "roles": [] }Issue with Teams 'Add a User to Group Chat' API call?
I am getting a very strange error when trying to add a new user to an existing group chat using a GraphQL call. I have looked through the documentation, asked AI, and even contacted Microsoft support and no one can seem to explain why this API call is failing. Below is the API call that I am making. I can find no reason that I should be receiving the error message '#microsoft.graph.aadUserConversationMember' To get the basic questions out of the way.... Yes, the account making the API call DOES have permission to add users to the channel (and can do so using the frontend as normal.) Yes, the thread in question is a group chat, so adding members to that chat should be a valid command. Yes, ALL members in the group chat currently have the type '#microsoft.graph.aadUserConversationMember', so it is definitely a valid type for users in this channel. Yes, I have tried both the beta and stable channel; each gives the same error message. Yes, the invited user is internal to our organization, and is a valid target for the invite (invites work through frontend as well.) No, I cannot use the 'add member to channel' endpoint, because the chat is a group chat, not a channel. I can only assume, at this point, that the error message is a red herring and there's something else wrong with my API call?Why am I receiving this error message when trying to add a member to a pre-existing group chat? Thanks in advance for any assistance.

I was working on an Excel file shared in a chat with members of a small workgroup. When it was ready to share with the larger team, I navigated to the appropriate Team > Channel, created a Post, clicked on + > Attach file > selected the file (which had been modified recently, so displayed on the pop-up). The team lead asked me to save it in a particular folder in the team's files, so I navigated to Shared (formerly Files)... and did not see it. I could briefly see it if I selected the "In messages" filter, but then after a moment that bugged out and displayed the "Something went wrong" error screen. This behavior persisted (briefly visible file list, then error screen) even after quitting Teams via the task bar and opening it back up. I did not want to create a separate version (especially now that the original file was linked in the Post), so I tried a few different methods to get it into Shared. I tried copying a link, but couldn't figure out a good way to paste it into Shared. I tried pasting it in a new Link, but that preserved it as a link/URL rather than a file -- serviceable but awkward. I checked whether there was an easier way to do it by opening in the web version, where Files is still active rather than Shared (same behavior, except no "In messages" filter so I couldn't test that). I poked around in SharePoint but didn't see anything interesting. I tried uploading a copy from within Shared by pasting the filepath from the "Save a Copy" dialog in Excel... ...and that's when I noticed a possible cause of the issue: another member of the original workgroup chat had created the file, and it was living in her Teams chat files, not mine. I then had her try doing it by navigating to her Teams chat files and selecting her copy, and then hallelujah, it appeared in Shared. I was able to drag it to the appropriate folder normally. Ultimately, I see two questions: Why does the file appear when the "In messages" filter is selected, but not otherwise? Why can I add a file saved in someone else's Teams chat files to a Post, but I can't upload it in Shared? Bonus: any idea why the "In messages" filter caused an error message to display?
Approval card not working when posted in a Power Virtual Agent Bot
In My flow I am posting the approval card to a Power Virtual agent Bot, I see the approval being posted properly but, response (Approve/reject) button click is not reaching 'Waiting for an approval'. Please suggest. Same works fine when approval is posted to 'Flow bot'.
Task Module shows popup but Adaptive Card does not render using M365 Agent SDK (Python)
I am using the new M365 Agent SDK for Python to return a Task Module (task/fetch). The popup opens successfully when I click the button in Teams, but the Adaptive Card inside the Task Module does not render. Instead, Teams shows the generic error: “Unable to reach app. Please try again.” My invoke handler returns the following structure: adaptive_card = { "type": "AdaptiveCard", "$schema": "http://adaptivecards.io/schemas/adaptive-card.json", "version": "1.4", "body": [ {"type": "TextBlock", "text": "Sample task module card"}, {"type": "Input.Text", "id": "notes", "isMultiline": True} ], "actions": [ { "type": "Action.Submit", "title": "Submit", "data": {"action": "sample_task_submit"} } ] } task_response = { "task": { "type": "continue", "value": { "title": "Dialog", "width": "medium", "height": "medium", "card": { "contentType": "application/vnd.microsoft.card.adaptive", "content": adaptive_card } } } } return InvokeResponse(status=200, body=task_response) Key symptoms: Task module window opens (so invoke is successful) Adaptive card does not render Shows “Unable to reach app” inside popup No errors in server logs This happens only with Task Modules; normal message replies work fine Questions: Is the above Task Module response format correct for the new M365 Agent SDK for Python? Does the SDK require a different return type or content-type for invoke responses? Are Task Modules fully supported in the M365 Agent SDK preview? Is there an example of returning a Task Module using the Python SDK? Any clarification or working sample for Python would be very helpful. Screen shot -App Validation Issue - Bot must send a proactive welcome message in personal scope
I'm working on a bot application for MS Teams using the Python SDK and encountered a challenge with app validation and the proactive welcome message requirement. What Happened: Initially, our bot handled the welcome message through on_installation_update, but app validation failed with the error: "Bot must send a proactive welcome message in personal scope." To satisfy validation, we added on_members_added_activity to send the welcome message for personal scope, which resolved the validation error. However, this created a new problem: on_members_added_activity is being triggered when we call the Graph API to query chats or users: {graph_url}/me/chats $filter=chatType eq 'oneOnOne' and installedApps/any(a:a/teamsApp/id eq '{teams_app_id}') {graph_url}/users/{user_id}/chats $filter=chatType eq 'oneOnOne' and installedApps/any(a:a/teamsApp/id eq '{teams_app_id}') According to a Stack Overflow discussion (https://stackoverflow.com/questions/57496329/proactive-messaging-bot-in-teams-without-mentioning-the-bot-beforehand), this appears to be a known issue: calling this API triggers a conversation update event even though there were no actual updates, resulting in duplicate events and duplicate welcome messages. Questions: What is the official/recommended way to handle known issue: calling this API triggers a conversation update event? Whats the recommended way to read personal chat history of a user? Should we be using a different approach for this app validation requirement? Any guidance or pointers to official documentation would be greatly appreciated!
Users on iOS can't write to group chat with a bot
Hi all, I'm seeing some strange behaviour with the Teams iOS app when trying to interact with bots in 1-1 group chats . I've tried with multiple iPhones, all updated to the latest Teams version. The same issue does not appear on Android and Web/Desktop flavours of Teams. Has anyone seen this issue before? I couldn't find anything in the knowledge base Setup: A group chat with two participants: one bot, one user Behaviour on web/desktop: User sees both participants of the group chat, user can send messages in the group chat Behaviour on Android: User can send messages in the group chat Behaviour on iOS (last tested with 6.13.1): User does not see the bot in the participants of the group chat: User cannot send messages in the group chat: (also notice the bot, which is correctly named "Symlabs9 - Symphony" in the messages on web/desktop, is shown as "Unknown User" on iOS) it seems Teams iOS is not counting the bot as a user? which would explain why the bot doesn't appear in the member list, and why the error about needing more than one person in the room is shown?
The Chat Notification Badge That Won't Die
I know there's another thread on this, but literally none of those solutions worked, so I'm a starting a new thread. My chat notification won't go away. All of my chats are read. Here's everything I've done to fix this already (note- It's a corporate computer so I can't mess with the anti-virus): Signed out of the app every (desktop, web, phone) Restarted my computer Cleared the cache data from all 13 different locations Changed the setting to close the app when I shut down Closed it in the Task Manager Turned off all of my notifications Clicked on every chat I've received over the last week The only thing that seemed to maybe be the culprit was a very large company meeting and I was the last to leave. There was a lot of chat in that meeting, though I didn't participate in any of it. The reason I think this was when I went to log into to Teams from my browser, as I started to type "Microsoft Teams" I noticed in the suggested sites that there was a chat message from that meeting. So obviously I've left the meeting. I've deleted that chat. I've even left the teams channel that hosts those meetings. For what it's worth, I don't have any notifications on the phone app (android). It's just on the desktop and the web. Please, for the love of god, help. It's slowly driving me insane and I don't have the mental capacity to deal with anything else that makes me insane during quarantine. 🙂 *jk- I'm fine. It's a joke*Teams Gains Ability to Start Chat with Email Address
A new Teams feature allows users to initiate chats with any email address. This caused some commotion in the security community, but it’s not that bad. In fact, it’s an extension of existing functionality that allows Teams users to chat with guest accounts. All that’s happening is that initiating a chat causes a new guest account to be created in the tenant, and there’s lots of controls to make sure that guests are controlled. https://office365itpros.com/2025/11/10/chat-with-email-address-teams/
