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!
Set 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
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.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.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.
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. POST to URL: https://graph.microsoft.com/beta/chats/[[THREAD_ID]]@thread.v2/members BODY: { "@odXXX.type": "#microsoft.graph.aadUserConversationMember", "roles": [], "email address removed for privacy reasons": "https://graph.microsoft.com/v1.0/users/[[USER_ID]]" } ERROR MESSAGE: {"error":{"code":"BadRequest","message":"The provided '#microsoft.graph.aadUserConversationMember' for 'odXXX.type' is not valid for this operation.","innerError":{"date":"2026-01-29T18:10:32","request-id":"<PII:moderator removed>","client-request-id":"<PII:moderator removed>"}}}
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:
