Regarding Teams Meeting Media Transport Behavior in VDI Optimization Scenario
Hello Microsoft Teams Engineering Team, I am currently working on a Browser Content Redirection / media offload implementation for a VDI environment, where WebRTC media transport is handled through a local native component while the Teams application continues running inside the virtual desktop session. While testing, I observed that: 1:1 calls successfully receive audio and video media But in meetings auido / video RTP is never forwarded despite successful ICE, DTLS, and SRTP establishment DTLS ApplicationData traffic is present during meetings, suggesting DataChannel/SCTP activity Based on transport-level observations, it appears that Teams meetings may rely on SCTP/DataChannel communication for SFU video subscription management, while 1:1 calls do not require the same subscription flow. I wanted to ask whether: Teams meeting video forwarding depends on active bidirectional SCTP/DataChannel connectivity Meeting video subscriptions are expected to be coordinated over the WebRTC data channel/control plane Split ownership of media transport and control-plane transport could affect expected Teams meeting behavior in VDI optimization scenarios Thank you for your time and guidance. Best regards,Rajdev
Adaptive Cards in Teams channel messages: fixed narrow width — request for width control
Hi Teams Platform team, We post structured status reports as Adaptive Cards into a Teams channel. The card consistently renders at a fixed width of 448 px on a 1080p display at 100% scaling with a maximized Teams desktop client — well below the available channel message stream width. Wide multi-column tables get truncated or wrapped, which significantly hurts readability. What we've tried No card-level `width` property exists in the Adaptive Cards schema. `msteams.width: "Full"` is documented to apply only to Stageview / task module / tab — silently ignored in channel messages (tested). Same payload via three delivery paths — Incoming Webhook, Logic App "Post adaptive card in chat or channel", and Microsoft Graph `POST /teams/{id}/channels/{id}/messages` — all render at the same narrow fixed width. The constraint is in the Teams channel-message renderer, not in any delivery layer. Minimal repro payload (7-column results table; all field names and values replaced with generic placeholders): { "type": "message", "attachments": [ { "contentType": "application/vnd.microsoft.card.adaptive", "content": { "$schema": "https://adaptivecards.io/schemas/adaptive-card.json", "type": "AdaptiveCard", "version": "1.5", "msteams": { "width": "Full" }, "body": [ { "type": "TextBlock", "text": "Pipeline Report — run-001", "weight": "Bolder", "size": "Medium" }, { "type": "Table", "gridStyle": "accent", "firstRowAsHeaders": true, "columns": [ { "width": 2 }, { "width": 1 }, { "width": 2 }, { "width": 1 }, { "width": 2 }, { "width": 1 }, { "width": 1 } ], "rows": [ { "type": "TableRow", "cells": [ { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "Col-1", "weight": "Bolder", "size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "Col-2", "weight": "Bolder", "size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "Col-3", "weight": "Bolder", "size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "Δ Col-3", "weight": "Bolder", "size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "Col-4", "weight": "Bolder", "size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "Δ Col-4", "weight": "Bolder", "size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "Status", "weight": "Bolder", "size": "Small" }] } ] }, { "type": "TableRow", "cells": [ { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "item-a", "size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "mode-x", "size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "0.000/0.000","size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "+0.00%", "size": "Small", "color": "Good" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "0.000/0.000","size": "Small" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "-0.00%", "size": "Small", "color": "Attention" }] }, { "type": "TableCell", "items": [{ "type": "TextBlock", "text": "✅ Pass", "size": "Small" }] } ] } ] } ] } } ] } `msteams.width: "Full"` is present but has no visible effect in the channel message context. Feature request Either of: Honor `msteams.width: "Full"` in channel-message context (not just Stageview/task module/tab), OR Add a card-level property (e.g. `msteams.channelWidth: "Full" | "Default"`) explicitly scoped to channel messages. Is this a known limitation with an existing tracking item, or should we also file it on the M365 Feedback Portal for upvotes? Thanks!
Feature Request: Real-Time Multilingual Voice Translation in Microsoft Teams
Hello Microsoft Teams Community, I would like to suggest a feature for Microsoft Teams that could help multilingual users communicate more naturally during meetings. Feature Idea: Each participant can speak in their own native language, and Teams will automatically translate and play the speech audio in the listener’s selected language in real time. Example: Telugu speaker talks in Telugu Kannada user hears Kannada audio Hindi user hears Hindi audio English user hears English audio This would be more powerful than subtitles because users can continue conversations naturally in their mother tongue without needing to read captions constantly. Possible Technologies: Speech-to-Text AI Translation Text-to-Speech Real-Time Voice Streaming Benefits: Better communication in multilingual countries like India Improved accessibility Easier collaboration for global teams More inclusive meetings I believe this feature could significantly improve communication in international and regional meetings. Thank you.Custom App (Static Tab) with SharePoint URL stays blank on first load in Teams Desktop Client
Hello Teams Developer Community, We have deployed a custom Teams app (v1.25) that uses a Static Tab to display our company's SharePoint intranet portal. The contentUrl and websiteUrl point to our SharePoint site. [The Issue] When a user clicks the app for the very first time in the Teams Desktop Client (New Teams), the screen remains completely blank (white loading screen). However, if the user clicks away to another app (like Chat or Teams) and then clicks back to our custom app, the SharePoint page loads perfectly. [Observations] This issue does NOT happen on Teams Web Client (browser). It loads instantly there. Clearing the Teams Desktop cache does not solve the problem. It seems to be related to WebView2 authentication/SSO redirect loops inside the iframe. I tried adding "showLoadingIndicator": true in Developer Portal, but the schema automatically strips it out upon saving. [Question] Is there a specific parameter we need to append to the SharePoint URL, or specific domains we must add to "validDomains", to prevent this initial blank screen caused by auth delays in the Desktop Client? Any guidance on handling this WebView2 rendering delay would be greatly appreciated. Thank you.
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.
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: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.
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.
