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!
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": [] }Microsoft Teams PowerShell Module 7.6.0 is broken
Dear Community I have a few Script with Microsoft Teams PowerShell, witch authenticate via Access Token. Everything works fine until latest Microsoft Teams PowerShell Module Update 7.6.0. I got following Error with the Script. Connect-MicrosoftTeams : Could not load file or assembly 'Microsoft.IdentityModel.JsonWebTokens, Version=8.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. If I downgrade my environment from Version 7.6.0 to Version 7.5.0 and rerun my script, the authentication is working as expected. What is wrong here with latest PowerShell Module 7.6.0 and how can I resolve the issue Many thanks for sharing any hint or tip ANDYCreate a calendar for a private channel
Good evening everyone, I need to create a calendar for a private channel. I was hoping someone could provide me with some advice on the best way to accomplish this with OOB Microsoft technology. I was thinking of creating a group calendar and having a PowerApp / Flow add items to it from the team's channel. Would love to hear some other thoughts on this. Any information is appreciated, HydeSet work location via API (Graph?)
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, Jens
