Immersive events in Microsoft Teams: Now generally available
We’re excited to announce the general availability of immersive events in Teams! This milestone brings 3D event experiences natively into Teams, making it easier to host engaging, interactive events that bring people together on PC, Mac, and Meta Quest devices. With immersive events, organizers can create tailored 3D environments where attendees join as avatars, interact naturally, and feel truly present. Because immersive events are built directly into Teams, you can plan, manage, and host immersive experiences using the familiar tools you already know – your Teams calendar, chat, and collaboration features. Simply open Teams, schedule an immersive event, and start designing your space. Immersive events can help drive enhanced engagement and connection for your workforce across multiple points of interest in a single branded event with a tailored experience—ideal for all hands, showcases, company events, new employee onboarding, and trainings. Note: With this general availability milestone, Microsoft Mesh is retired as of December 1, 2025. Read further for more details on this transition. Designed for flexibility and connection Immersive events in Teams deliver everything you need to create a deeply engaging experience, whether hosting a small internal meeting or a large organizational event. Build your event space your way Customize your venue with your brand logos, images, 3D models, videos, text, and interactive elements, and even sequence the experience for storytelling and impact. The intuitive editor enables creative freedom without the need for coding skills. Start faster with pre-designed templates Choose from ready-to-use 3D environments tailored for common event types such as all-hands meetings, webinars, and team celebrations. Deliver with confidence Presenter tools simplify setup and execution, with one-click starts, integrated Q&A, and efficient attendee management so you can focus on the message, not the logistics. Stay secure and compliant Immersive events inherit the same enterprise-grade identity management, security, and privacy protections built into Microsoft 365.

Enterprise-ready VR deployment Set up Meta Quest devices quickly with identity integration and MDM enrollment, ensuring secure, compliant sign-in to immersive events. Bring your event to life with action groups Make events more immersive and memorable. Action groups in Teams let you create dynamic, interactive experiences without writing a single line of code. Instantly trigger animations, play audio or video, reveal content, and switch visuals on the fly. Whether it’s launching a welcome sequence, powering a live quiz, or showcasing a 3D model, action groups give organizers controls to engage audiences in real time. Licensing Hosting immersive events in Teams requires: A qualifying commercial Teams license, and A Teams Premium license, which enables immersive event capabilities. Co-organizers and attendees only need a standard Teams license, such as Microsoft 365 E3/E5 with Teams or Teams Enterprise. Transition from Microsoft Mesh The general availability of immersive events in Teams follows the previously announced retirement of Microsoft Mesh as a standalone platform. This change reflects our continued investment in bringing immersive experiences into Teams for a more integrated and scalable 3D meeting solution. As of December 1, 2025: Users will no longer be able to attend Mesh events via the Mesh PC or Quest apps. The “Immersive space (3D)” view in Teams meetings will be removed. Joining Teams meetings via the Mesh Quest app will be disabled. The “mesh.cloud.microsoft” website will be decommissioned. If your organization has relied on Mesh for immersive meetings or events, now is the time to transition to immersive events in Teams, in order to take advantage of these new experiences. Get started today Creating an immersive event in Teams is simple: Open your Teams calendar. Select New event, then choose Immersive event. Customize your environment, invite participants, and host your event. Help prepare your organization for immersive events in Teams (includes optional Meta Quest deployment guidance), and learn how to get started with immersive events in Teams to transform your next online event into a high-impact 3D experience.

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!
Would Microsoft Teams SDK for Python (Preview) affect marketplace submission
Hi, I need to know if it's possible to publish a custom teams app and get validated to have the app in marketplace for public if it's developed using Teams SDK with python which is mentioned as still in preview. Teams SDK is now generally available for JavaScript and C#, supports Python in developer preview https://learn.microsoft.com/en-us/microsoftteams/platform/bots/overview https://learn.microsoft.com/en-us/microsoftteams/platform/resources/dev-preview/developer-preview-intro?tabs=new-teams-client https://github.com/microsoft/teams.py Thank you!
