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/
Issue with Teams Notification Only Chatbot(Android)
Hi, We are developing a teams chat bot which is notificationOnly. but we observed that the chat is enabled on Android devices even though its notification only. its disabled in all other devices like desktop and ipad/ios but not on android(phone).please see the screenshot below.i captured it on my desktop and those test messages are sent from my android phone where the chat is supposed to be disabled everywhere.Support RTL Languages on MacOS
As now, It seems Microsoft teams on MacOS does not support RTL languages when texts are being typed. This makes bad feeling when users want to read the text they've typed. The issue becomes worst when the text contains English phrase (when the message is sent) As far as I remember, Skype did support RTL languages when the texts are being typed.
Unable to Add Tabs to Chats Consistently in Teams via GraphAPI
Expected Behavior: Tabs should be consistently added to chats when using the Graph API, provided all necessary permissions and conditions are met.Description We are encountering an issue when using the Microsoft Graph API to create chats and https://learn.microsoft.com/en-us/graph/api/chat-post-installedapps?view=graph-rest-1.0&tabs=http and https://learn.microsoft.com/en-us/graph/api/channel-post-tabs?view=graph-rest-1.0&tabs=http in Microsoft Teams. While we have the necessary permissions, the process of adding a tab to a chat works intermittently. Sometimes the tab is successfully added, but most of the time it fails, even though the app is installed correctly, with the following error: Failed to execute MsGraph backend request GetUserLicenseDetailsS2SRequest. Workload MsGraph_DirectoryServices. Request Url: https://graph.microsoft.com/v1.0/users/c0cfdd6b-d64d-42e1-8111-0881725f68ff/licenseDetails?$select=skuId,skuPartNumber,servicePlans, Request Method: GET, Response Status Code: NotFound, Response Headers: Strict-Transport-Security: max-age=31536000\r\nrequest-id: c86b5fbd-4224-486b-8f3e-8ad3f561a377\r\nclient-request-id: c86b5fbd-4224-486b-8f3e-8ad3f561a377\r\nx-ms-ags-diagnostic: {\"ServerInfo\":{\"DataCenter\":\"North Europe\",\"Slice\":\"E\",\"Ring\":\"4\",\"ScaleUnit\":\"011\",\"RoleInstance\":\"DB1PEPF00075073\"}}\r\nx-ms-resource-unit: 1\r\nDate: Tue, 22 Apr 2025 09:47:03 GMT\r\n, Reason Phrase: Not Found, Request ID 1F9FFBD00A5F489E9B7CABDCFB857858. Reproduction steps: Create an AAD App registration with required application permissions (to install apps and manage tabs in chats), ie at least the following: TeamsAppInstallation.ReadWriteAndConsentForChat.All TeamsTab.ReadWriteForChat.All Create a Teams application with a static tab with "groupChat" scope Install app in chat: POST https://graph.microsoft.com/v1.0/chats/:chatId/installedApps with body below Add (pin) tab to chat: POST https://graph.microsoft.com/v1.0/chats/:chatId/tabs with body below {"email address removed for privacy reasons" : "https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/{{AppId}}"} Expected Behavior: Tabs should be consistently added to chats when using the Graph API, provided all necessary permissions and conditions are met. Current Behavior: The process of adding tabs to chats is unreliable. Sometimes the tab is added, but most times, the request fails without clear reasoning. All required permissions appear to be in place since it works occasionally. Note that this issue started to occur at the beginning of the month, around the 8th of April apparently, has anything changed around this date? Also note I also found traces of https://learn.microsoft.com/en-us/answers/questions/2259024/add-tab-to-chat-request-stopped-working-now-it-ret?source=docs in our logs but it is apparently resolved now.Teams Adaptive card Textrun is rendering markdown
I am making bot alarm message using adaptivecard. It is important for me to print out the user name and email accurately. So I tried to use TextRun to prevent markdowns from being supported.(https://adaptivecards.io/explorer/TextRun.html) But there is a problem that textrun is being marked down on ios mobile, tablet. this is my adaptive card json. {"type":"AdaptiveCard","$schema":"http://adaptivecards.io/schemas/adaptive-card.json","version":"1.3","body":[{"type":"TextBlock","text":"**Microsoft Entra ID**","size":"Large","wrap":true},{"type":"TextBlock","text":"user 5","size":"Medium","wrap":true},{"type":"RichTextBlock","inlines":[{"type":"TextRun","text":"- ``Use `code` in your Markdown file.(~~hspark~~@aaa.co.kr)\n","size":"Small"},{"type":"TextRun","text":"- + First item(test'email address removed for privacy reasons)\n","size":"Small"},{"type":"TextRun","text":"- ** test12041432(test'''email address removed for privacy reasons)\n","size":"Small"},{"type":"TextRun","text":"- > test12041435(test''email address removed for privacy reasons)\n","size":"Small"},{"type":"TextRun","text":"- 1. adsfsdafsdf *{}*asdfadsf*_~ark~(test'''email address removed for privacy reasons)","size":"Small"}]},{"type":"TextBlock","text":"user 5","size":"Medium","wrap":true},{"type":"RichTextBlock","inlines":[{"type":"TextRun","text":"- ``Use `code` in your Markdown file.``(~~hspark~~@aaa.co.kr)\n","size":"Small"},{"type":"TextRun","text":"- + First item(test'email address removed for privacy reasons)\n","size":"Small"},{"type":"TextRun","text":"- ** test12041432(test'''email address removed for privacy reasons)\n","size":"Small"},{"type":"TextRun","text":"- > test12041435(test''email address removed for privacy reasons)\n","size":"Small"},{"type":"TextRun","text":"- 1ASDFASDFSADFASD asdfadsfsd *{}*adsfasdf*_~ark~(test'''email address removed for privacy reasons)","size":"Small"}]}]} I used \ to escape markdown on textblock, but there was a phenomenon where \ for escape was output together on mobile (Android, ios) even though it was properly rendered on pc. i want to know: Is there any way to output properly without markdown on adaptive card? PC, mobile, table should be supported in all environments. and I think it's a bug that textrun is rendered as a markdown in ios environment so please solve it. that's adaptive card json rendering exapmle pc: ios mobile: and escape \ example: mobile: pc:Questions About Alternatives to Multi-Tenant Bots After July 31, 2025 Deprecation
Hello, As the ability to create multi-tenant bots in Azure will be discontinued after July 31, 2025, I’d like to ask if there are any viable alternatives available now? If I create a single-tenant bot and publish it to the Teams App Store, will users from other tenants still be able to interact with the bot? Additionally, will the bot be able to access their basic user profile information (only user name and aadObjectId) and conversation data? From my understanding, access tokens obtained using the client ID and client secret are tenant-scoped, meaning they are not valid across other tenants. As a result, the bot cannot access user information such as profile photos or email addresses from users in other tenants — is that correct? I'd really appreciate any clarification or recommended best practices on this. Thank you!
