Copilot Studio bot in Teams occasionally sends duplicate responses
I’m using a Copilot Studio bot deployed in Microsoft Teams, and I’m experiencing an intermittent issue where a single user message occasionally triggers two identical responses. This does not happen consistently, and there is no intentional duplicate logic in my bot design. I’m not sure whether this is caused by duplicate message delivery from Teams (e.g., retries or at-least-once delivery behavior), or something within Copilot Studio itself. Is this a known behavior for the Teams channel or Copilot Studio? Are there any recommended ways to detect or prevent duplicate responses at the bot level? Any insights or best practices would be appreciated.Copilot Studio in Teams sometimes wraps user input with HTML tags (e.g., <div>)
I’m using Copilot Studio deployed to Microsoft Teams, and I noticed that user messages are occasionally received with HTML tags. For example, when a user sends "get me the onboarding status", sometimes it displays in the dialog box as "<div>get me the onboarding status</div>" This does not happen consistently. I’m not sure whether this is caused by how Teams renders or sends messages (e.g., HTML vs plain text), or if it is something specific to Copilot Studio. Is this expected behavior for the Teams channel? Any clarification or recommended handling would be appreciated.
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.

Web Notifications API from Personal Tab app doesn't work
I have a client-side web application that we're trying to get to run as a Teams personal tab app. I have the app working as a teams app, as long as we "open in new window" so that the app doesn't get put to sleep as it needs a permanently up session with something else. Our app uses Web Notifications API (https://developer.mozilla.org/en-US/docs/Web/API/Notification) to create desktop notificiations, but this does not seem to work when running as a Teams tab app popped out into a new window. No notifications are displayed. Permissions have been requested correctly and given and Windows is set to allow notifications, but these web notifications never make it out of teams to the desktop. There are no errors in the browser console to say the web notifications are not supported in Teams. Is this not supported as a teams app? The inbuilt activity feed is useless for our purpose (for a few reasons), so please don't suggest I use graph to make use of that instead.ad-hoc call transcripts via graph api endpoint
I have an app with the below permissions. I can successfully get list of transcripts and transcript content for online meetings. But when I try to get list for ad-hoc calls, I get the 400 Bad Request error. Any suggestions on how to get ad hoc call transcripts? Permissions Error:
[Adaptive Card] Issue with rendering images and ToggleVisibility
I am using a simple accordion style adaptive card with a collapsible section: { "type": "AdaptiveCard", "$schema": "https://adaptivecards.io/schemas/adaptive-card.json", "version": "1.5", "body": [ { "type": "Container", "items": [ { "type": "ColumnSet", "columns": [ { "type": "Column", "items": [ { "type": "TextBlock", "text": "Title", "wrap": true, "size": "Medium" } ], "width": "stretch" }, { "type": "Column", "id": "chevronDown", "spacing": "Small", "verticalContentAlignment": "Center", "items": [ { "type": "Image", "url": "https://adaptivecards.io/content/down.png", "width": "20px", "altText": "collapsed" } ], "width": "auto" }, { "type": "Column", "id": "chevronUp", "spacing": "Small", "verticalContentAlignment": "Center", "items": [ { "type": "Image", "url": "https://adaptivecards.io/content/up.png", "width": "20px", "altText": "expanded" } ], "width": "auto", "isVisible": false } ], "selectAction": { "type": "Action.ToggleVisibility", "targetElements": [ "cardContent", "chevronUp", "chevronDown" ] } }, { "type": "Container", "id": "cardContent", "isVisible": false, "items": [ { "type": "Container", "items": [ { "type": "TextBlock", "text": "Text" } ] } ] } ], "separator": true, "spacing": "Medium" } ] } On the initial load, the image (down arrow) gets rendered properly. If I click on it, the collapsed section opens (and the down arrow gets hidden and replaced by the up arrow). However, if I collapse the accordion again, the following happens: And it stays like this until I restart the Teams client. Looking at the devtools network tab for the web client the following behavior can be observed: During the initial load (1) the down.png gets fetched and stored in memory. You can also see the result on the right. If I extend the component (2), the up.png gets fetched and stored in memory. If I then collapse the section again (3), the call to memory for the down arrow fails with GET blob:https://teams.microsoft.com/51e89b2e-7da4-4c80-bf98-a6ee4d257052 net::ERR_FILE_NOT_FOUND It happens in both the standalone client and the web version. Also for multiple users (so it is not just some caching issue on my side). It seems to me that toggling the visibility somehow removes the images from memory. But it only happens for images that are initially visible (it doesn't happen for the up arrow in my case).Create Bot without Developer Studio
Hi, We have a bit hard policies and users are not able to use the Developer Studio by they own to make new Bot: If you press [New Bot] you can give the name, but then [Create Bot] start hanging and does nothing. Previously on Azure had a user setting which block or allow users to register apps. Now I need our tenant admins or application administrators (?) to setup the bot(s) manually. Does anybody knows if the bot registration for Teams is possible to do without developer studio? The Developer Studio shows only your own Bots, so they cannot do that for me using Developer Studio.
Is there a way to get live transcript in Microsoft Teams?
I am trying to find a way in Microsoft Teams to get the live transcript, I want to be able to subscribe to a meeting/call that it is still running and to get the transcript from it. I understand that there is an Graph API that allows me to get the transcript for a meeting/call that ended, but that's not what I need. I am alright even with faking the subscription and do a HTTP call every 2-5/seconds. After I get the transcript I would like to do some live processing on the text. I am aware that I can connect a bot to a meeting/call and then the bot can interact with the audio stream and use Azure AI Speech Service to convert the Speech-To-Text and get the live text. I found a sample in Microsoft Github repos: https://github.com/microsoftgraph/microsoft-graph-comms-samples/tree/master/Samples/PublicSamples/EchoBot This is a good solution, but if possible I would like to do be able to do one of the following, if possible: get the transcript without a bot that needs to be connected to a session. connect a bot that can interact with the live transcript in order to get all additional metadata, like speaker name.
SSO for a Python Teams Bot (M365 Agents SDK + FastAPI) — Single-Tenant, Multi-Tenant, and UAMI
We're building, a Teams bot (Python / FastAPI) that uses the M365 Agents SDK (microsoft-agents-hosting-fastapi + microsoft-agents-authentication-msal, v0.8.0) with a CloudAdapter and MsalConnectionManager. The bot is currently scoped to personal only and runs behind an Azure Bot resource. We are trying to implement SSO to authenticate users, so far we are not successful. The main blocker is that we failed to authenticate users from tenant different than the Azure Bot resource of our app. If anyone has successfully managed to authenticate users on Teams using a setup similar than ours please do share your experience. We would love to learn from your experience. So far this was our main source of documentation: https://learn.microsoft.com/en-us/microsoftteams/platform/bots/how-to/authentication/bot-sso-overview Many thanks
