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!
Would Microsoft Teams SDK for Python (Preview) affect marketplace submission
Hi, I need to know if it's possible to publish a custom teams app and get validated to have the app in marketplace for public if it's developed using Teams SDK with python which is mentioned as still in preview. Teams SDK is now generally available for JavaScript and C#, supports Python in developer preview https://learn.microsoft.com/en-us/microsoftteams/platform/bots/overview https://learn.microsoft.com/en-us/microsoftteams/platform/resources/dev-preview/developer-preview-intro?tabs=new-teams-client https://github.com/microsoft/teams.py Thank you!Adaptive card do not render image on Teams Desktop
Hello Community, We are facing a challenge with the image rendering in our Adaptive cards only in the Teams Desktop application. All is working fine with the Teams on the Web, and when we test it in the https://adaptivecards.io/designer/ The images are stored in our SharePoint. Will this be the problem ?

All Teams Bots Not Working At All
This morning all of a sudden all our Teams bots stopped working. These are bots built using bot framework running on Azure Bot Teams Channel. Is this related to the current Teams API issue we talking about? All of a sudden all our client and test bots stopped working. But the Web Channel is working as expected. Only the teams channel. We even checked with ngrok and its not even hitting the service. We checked the app registrations and their credentials as well to ensure not issues there too. Completely lost whats happening. Help?
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?

Hey community! The new work hours and location feature is rolling out for Outlook and Teams: https://blog.admindroid.com/work-hours-and-location-in-outlook-for-efficient-collaboration/ Does anyone know who to read and write this information (especially the location) via API / Microsoft Graph? This is a nice feature and we would like to set this programmatically. Thank you very much! Best regards, JensHow to create an audio calling bot for the Marketplace?
What is the correct set of framework(s)/tools that allow a bot to make audio calls to teams users that can be installed to multiple customer's Teams instances, and added to the Teams Marketplace, as of January 2026? It seems that there is a lot of transition going on in the various bot frameworks that are supported by Microsoft. The new Microsoft 365 Agents https://github.com/microsoft/Agents/issues/377 , and won't do until at least March 2026. The Teams Microsoft Graph Comms libraries still work and appear to be current, however that is only half the puzzle. I need to also package up the bot that has been built, including build an app manifest, etc. The AzureBot still works, but upon packaging up, it seems that Multi-tenant support was https://github.com/microsoft/botframework-sdk/issues/6698. The permissions for the various Microsoft graph https://github.com/microsoftgraph/microsoft-graph-comms-samples do not match up with the permissions for the packaging of the new agent (e.g. Calls.AccessMedia.All, Calls.Initiate.All are required, but not present). It also isn't clear to me Microsoft Graph App Manifest can help in this matter. Any clarity on the matter would be much appreciated. This is kinda urgent, so can't wait until Agent SDK
