CSS Properties being stripped from Teams Chat messages from Bot
Hi Team, We've noticed that certain CSS properties are no longer appearing in HTML messages when sent to Teams Chat. Previously, our bot styled messages using display and border properties, but now these properties are missing from the HTML when we inspect the page. Steps to Reproduce: Start the Echo bot from the sample templates (I used Teams Toolkit to deploy it to Teams or run it in the Test tool). In the TeamsBot.ts file, modify the onMessage function by replacing await context.sendActivity(...) with the following code. This example adds styling to an echo message. const a: Partial<Activity> = { text: `<span style="display: block; color: red; border-radius: 4px; padding: 4px; border: 1px solid red; ">Echoo:</span> <span style="display: block;">${txt}</span>`, textFormat: TextFormatTypes.Xml }; await context.sendActivity(a); Note: I also tried sending the HTML directly with context.sendActivity(...) without setting the textFormat property in the Activity, and observed the same result. Run the bot in the Test tool and Teams to compare behavior. Observed behavior: In the Test tool: All styles are applied as expected. In Teams: Only the color property is applied, while display, padding, and border properties are ignored (stripped out of the HTML). Here’s an example of the HTML output in Teams: <div dir="auto" id="content-1730973548675" aria-label="Echoo: test styles properties" class="fui-Primitive ___16zla5h f1oy3dpc fqtknz5 fyvcxda"> <span style="color: red;">Echoo:</span> <span>test styles properties</span> </div> Could you provide insights on whether this change is intended, and if there are any workarounds for preserving these CSS properties in Teams messages? Thank you!
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?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.
Sign In button stopped being shown in MS Teams
Good afternoon, Today we encountered the issue: the Sign In button stopped being shown within the Sign In prompt of OAuthPrompt class: We use this class for SSO in MS Teams in our solution for several years without any issues and changes. The implementation is done exactly as suggested in samples and according to documentation from the links below: https://learn.microsoft.com/en-us/javascript/api/botbuilder-dialogs/oauthprompt?view=botbuilder-ts-latest https://github.com/microsoft/BotBuilder-Samples/blob/main/samples/javascript_nodejs/18.bot-authentication/dialogs/mainDialog.js Here is our code: // Prompt for OAUTH this.addDialog( new OAuthPrompt(ComponentDialogConstants.OAUTH_PROMPT, { connectionName: process.env.MS_CONNECTION_NAME, title: 'Sign In', timeout: 300000 })); The productive usage of our clients' integrated bots is affected. The issue is reproduced in all the environments for old, new version of MS Teams and in Web, so there is no workaround. Therefore please consider this issue with the priority very high. Thank you, Best regards, DaryaBot Image Attachment Does Not Display on MacOS.
We are developing a bot which renders and sends png images back to the user. On mobile and Windows builds of Teams, we are able to display the image within an Attachment using either a remote url or the base64 png data. However, on MacOS builds, the chat displays a narrow vertical box without the image rendered in it. Selecting a reaction, thus making the attachment wider, displays a very small render of the image without any click functionality. I should note that this issue only appears to effect individual chats with the bot; it works as expected in if used in a channel. Additionally, this issue came up only within the past week and appears to be unrelated to any changes in our code during that time. This is Teams release 1.4.00.22368 on MacOS 11.5.1 var imageAttachment = new Attachment { ContentType = "image/png", Name = "Chart", ContentUrl = pngUrl, Content = new FileDownloadInfo(pngUrl) };
Can we send private message in Microsoft Teams using bot on behalf of user in Teams ?
We can send private messages from a Microsoft Bot to a Teams user. It appears as a chat between bot and a user. But I need a functionality where a bot can send message on behalf of user in Teams and it would exactly appears as a 1:1 chat of two users in Teams, not as a chat between bot and a user.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": [] }Format for sending images to Azure OpenAI
Hi, I logged into Azure OpenAI Studio and tried to send an image in the OpenAI chat. The image was successfully sent, and OpenAI provided a correct response based on the error message in the image. While checking the backend code for sending the image to the OpenAI client, I couldn't find the exact format required for the image URL. What should be the format of image url. I have tried it out by sending as base 64 and i didnt get any proper response. // Initialize the AzureOpenAIClient var azureClient = new AzureOpenAIClient(new Uri(endpoint), credential); // Initialize the ChatClient with the specified deployment name ChatClient chatClient = azureClient.GetChatClient("gpt-4o"); // Create a list of chat messages var messages = new List<ChatMessage> { new UserChatMessage(" image_url "), new AssistantChatMessage("The error message \"We couldn't upload your data.
