What’s New in Microsoft Teams | December 2025
As 2025 comes to a close, I want to thank you all for being part of the Microsoft Tech community! Your suggestions and feedback have been incredibly impactful as we’ve continued working toward our goal of making Teams smarter, more secure, and easier to use. In 2026, you can look forward to new ways to collaborate and do more, with Teams as the platform where people and agents collaborate together. We hope you’ll keep sharing your experience with new Teams features in the new year! To wrap up the year and lead into the next, we’re announcing some new features that can help you customize Teams for the way you like to work and make your conversations and connections more secure. “Pop out core Teams functions into a new window” gives you the ability to organize the elements of Teams that you use most frequently however you want on your desktop. “Tenant-Owned Domain Impersonation Protection for Teams Messaging” analyzes the identity and domain authenticity of external users when they make their first contact with you, to make sure they’re not impersonating your organization’s domain. These and all the other features below are now available, so give them a try and let us know what you think. Best wishes for a very happy and productive start to 2026! Chat and collaboration Meetings, webinars, and town halls Teams Phone Fundamentals and Security Frontline Worker Solutions Certified for Teams Devices Chat and Collaboration Pop out your core Teams functions into a new window You can now organize your work environment to fit your needs by opening Teams chat, calls calendar, activity, and more in separate windows. This gives you the flexibility to multitask and organize your workspace the way you want. Whether you're catching up on chats while reviewing call history or managing notifications alongside your calendar, this update helps you stay productive without switching tabs. Simply right-click an app icon or use the app flyout to pop it out into its own window. Joining a private team by code now requires owner approval Joining a private team using a code now requires a team owner’s approval. This update gives team owners more control and boosts security by ensuring every new member is approved even when using a Join code. This helps prevent unintended or unauthorized access to private teams while keeping code-based joining convenient for those who are authorized. Meetings, webinars, and town halls Enhancements to Interpreter and multilingual meeting experience Spoken language is now automatically detected and updated across Interpreter, live captions, and live transcription when Interpreter is enabled, keeping all speech features consistent with the language being spoken – no manual setup required. When Interpreter is disabled, live captions and transcription will still work, but auto-update spoken language will not be available, and meeting participants will need to speak in the spoken language manually selected in the meeting settings to ensure accuracy. Additionally, a new “preparing” status provides clear visual feedback while Interpreter initializes, helping users know when the system is ready – especially important for multilingual meetings. Interpreter settings have also been improved with concise explanations for each configuration and field, making setup easier and minimizing confusion. Teams Phone Microsoft 365 Copilot chat in Calls app post-calling experience – Generally available The post-call Copilot experience for Teams Phone on desktop and in mobile is now powered by Microsoft 365 Copilot Chat. After a call ends, users can open Microsoft 365 Copilot Chat as a side panel in the Teams ‘Calls’ app to generate summaries, surface key insights, and get suggested next steps. By using data from Microsoft Graph and the web—not just the call transcript—Microsoft 365 Copilot Chat delivers responses that are more personalized, relevant, and actionable, helping users quickly move from conversation to follow-up. Compliance Recording ISV Support for Call Queues in Microsoft Teams Phone Teams Phone now supports third‑party ISV compliance recording at the call queue level, giving organizations a simpler and more consistent way to meet regulatory requirements. Recording is applied at the queue—rather than per individual calling representative—so every call routed through that queue is automatically captured by the organization’s chosen compliance solution. This approach is especially useful for large enterprises and dynamic support teams where calling representative membership frequently changes. Admins can apply a single queue-level policy to ensure all incoming calls are recorded compliantly without managing individual calling representative user settings. Learn more. Fundamentals and Security Tenant-Owned Domain Impersonation Protection for Teams Messaging Own Domain Impersonation Detection in Teams identifies if an external user comes from a domain that is impersonating the recipient tenant's own domains during their initial contact with an enterprise user via Teams messages. This helps to protect users from bad actors spoofing tenant domains by analyzing sender identity and domain authenticity in real time, alerting users to suspicious activity and reducing phishing risks across messaging. Frontline Worker Solutions Frontline Hub Say goodbye to scattered tools and fragmented workflows. Frontline hub brings everything you need to deploy, manage, and monitor frontline Teams experiences into one streamlined destination—now available on the manage frontline teams page in the Teams Admin Center. With dynamic recommendations tailored to your deployment journey, frontline hub helps you deploy faster, simplify management, and deliver connected experiences that empower your frontline workforce.

Library switching removed
I just realize that the library switch feature is not available anymore in Teams (reachable from the main channel) We are now forced to open in SharePoint to access this feature. This is a lost of productivity for users who want to access other libraries in the site... I can't understand why this was removed. Is there a technical reason?

Best AI Agent for HR in Microsoft Teams?
So our HR team is looking for an AI agent tool that fits into our HR processes, such as performance reviews, 360 feedback, policy management, etc. We've messed around with Copilot and while it has been solid for productivity overall, it doesn't quite handle the HR processes. Any recommendations?
Unable to remove old account sing up form Teams on Mac OS
I cannot remove an old sing account from Teams on Mac OS. I have to delete the keychain, I delete the temp folder, and remove and reinstall Teams, and the old account is still there. I have a case open with the Microsoft team, and they cannot figure it out. Where is the login info store, and why has Microsoft not provided a solution where users can remove accounts as easily as they can add? Please help!Unleashing the power of agents in Microsoft Planner
In today's fast-paced world, AI has become an essential tool for enhancing productivity and efficiency. We are committed to empowering our users with innovative solutions that simplify their work processes, and we’re thrilled to introduce the latest updates to Microsoft Planner, designed to leverage the power of Copilot and agents to streamline project management and task organization. With the recent announcement of Project Manager agent, rolling out in public preview in the Planner app in Microsoft Teams, and the rollout of the new Planner for the web, we are bringing you a comprehensive suite of tools to help you and your team achieve more with less effort. We invite you to explore these exciting new features and discover how they can transform the way you work. Introducing Project Manager agent Project Manager agent is a new AI-powered agent designed to enhance your planning experience by acting as a virtual project manager within your plans. Project Manager agent is built to streamline your planning process, empowering you to focus on the strategic aspects of your work while it handles some of the tasks on your behalf. It is the latest development in enhancing and transforming team collaboration with AI in Planner. Earlier this year, we introduced Copilot in Planner (preview) as a personal companion experience designed to work alongside your planner workflow. With Project Manager agent, we’re now bringing AI capabilities directly into your plans, allowing you to interact with the agent as an integral part of your plan. Project Manager agent takes your goals and automatically breaks them down into actionable tasks. But it doesn’t stop there, it can also execute these tasks on your behalf. By managing the plan and executing tasks, the agent enables you to focus on impactful decisions while it contributes directly to the success of your project. When you start a plan with Project Manager agent, it guides you to define a goal you want to achieve (for example, conducting research on a specific topic). The agent will then generate all the necessary tasks for the research topic. Assign these tasks to the agent, and it will execute on them, providing detailed output that is automatically captured in a Loop page embedded within each task. All members of the plan can collaborate directly within the Loop page, exchanging comments and feedback with the Project Manager agent. Upon selecting Regenerate, the agent incorporates the feedback and generates a refined response, improving the task outcomes. At any point, if Project Manager agent does not have adequate information to generate necessary output, it will even ask clarifying questions that will allow it to provide better responses. You will notice that Project Manager agent is capable of contributing at every step of your plan, delivering value throughout the process. This comes with a new Project Manager View in Planner—your hub for setting goals, generating tasks, and showcasing the execution status. This intuitive interface lets you set your project goals and generate tasks, assign tasks to team members or the agent for execution and track progress and statuses in real time. Additionally, in the board view, you can also group tasks by Project Manager, which shows all the Project manager tasks and status in the appropriate buckets. At its core, the Project Manager agent runs on the Multi-Agent Runtime Service (MARS), a platform built on Microsoft Autogen. MARS leverages specialized agents with unique expertise, enabling the Project Manager agent to perform effectively across diverse scenarios. See the blog post to learn more about how Project Manager agent and MARS function. To help you get started, we’ve provided predefined, customizable templates on various topics, allowing you to quickly kickstart a Project Manager plan and easily tailor it to meet your specific goals. Once you’ve selected a template, you can modify the plan to align with your specific needs and goals, ensuring it meets your unique requirements while leveraging the agent’s capabilities for streamlined execution. From idea, to plan, to done, the Project Manager agent is your trusted partner, ensuring every aspect of your plan is managed seamlessly. We’re also introducing the Microsoft Whiteboard canvas in Planner! This new feature allows you and your team to brainstorm directly within the context of your plan. Upon creating a new plan with the Project Manager agent, you will now see a Whiteboard tab in the plan. Whiteboard offers a dynamic and collaborative canvas within Planner, allowing users to easily convert ideas into tasks and streamline workflow from ideation to action. In the canvas, you and your team can engage in real-time collaboration using inking, sticky notes, and templates. With the Planner integration, you can quickly convert your notes to tasks in one click, directly adding them to your plan. We’re excited to bring these powerful tools to your planning experience, and we can’t wait to see the impact of the Project Manager agent in your daily workflows! The new Project Manager agent will be rolling out to public preview in the Planner app in Teams in the coming weeks. To explore these capabilities, customers are required to have a Microsoft 365 Copilot license and also need to ensure their current Microsoft 365 licensing allows them access to Microsoft Loop. As this is a preview release, please note that the features may evolve based on user feedback and ongoing improvements. Initially, Project Manager agent will support English language as the interaction medium, and other languages in the future. We’d love for you to try it out and share your thoughts to help shape its future development! Please select the thumbs up or thumbs down button in the Project Manager view or in the Task details to share what you think about the experience. In addition, we are announcing two more capabilities that will be coming soon to Microsoft Planner: 1. Copilot in My Tasks view: This feature brings AI-powered organization and prioritization to your tasks, helping users effectively manage their backlog and enabling them to stay on top of what matters most. 2. Automated status report emails: Provides the capability to automatically generate a status email from your plans, streamlining the process of sharing weekly updates so you can spend less time on emails and more time moving projects forward. We expect these features to be available for our customers to try early 2025. Join us at Microsoft Ignite to learn more about Project Manager agent in our breakout session, "Boost productivity with Copilot in Microsoft 365 apps." Try Planner for the web today! The new Planner for the web is now available! This marks another major milestone in the Planner journey that we announced last November at Ignite.

Planner for the web now brings together the simplicity of Microsoft To Do, the collaboration of Planner, the power of Project for the web, and the intelligence of Microsoft 365 Copilot into a simple, familiar experience. Discover a new way to manage tasks for individual plans, team initiatives, and larger scale project management aligned to goals and key strategic objectives. We’re excited for you to try it out and share your thoughts. Thanks to your ongoing feedback, we’re continuing to roll out bug fixes and new enhancements regularly to both Planner in Teams and Planner for the Web. We have more exciting updates coming soon including the availability of Planner for the web in GCC, a new board view in the My Tasks view, an updated experience for the Planner app in Teams channels, and more. Check in regularly on the roadmap to learn about what’s coming. Explore the new Portfolios feature The frequently requested Portfolios feature is also rolling out in the Planner app in Teams and will start rolling out in the new Planner for the web app in the coming weeks! This powerful addition is designed to help you effortlessly manage and track progress across multiple plans. With Portfolios, you can now get a consolidated view of all your premium plans and tasks, ensuring nothing slips through the cracks. Whether you're coordinating between teams or looking for a top-down perspective, Portfolios in Planner makes it all possible in one location, streamlining workflows and enhancing collaboration.

Hello Teams Community, I'm facing a strange issue with App notifications in Microsoft Teams. I've already researched this and found nothing. I've opened a Microsoft case and I'm waiting for an answer but it's taking longer than expected. So, I'm turning to you for expedited help! Scenario: You're an administrator in Teams. You've applied a setup policy for a pinned app like Viva Engage. After the policy is applied and the tool is launched, users complain that notifications are either too frequent or not frequent enough. You direct them to the Teams Notification and activity settings to control app notifications. The users go to Teams notification settings but report back to you that the App section of Teams settings doesn't exist. Problem Statement: Microsoft explicitly states in their documentation that in order for the App notifications section to appear, you must first add an app yourself within Teams and get at least one notification. But relying on users to add an app, somehow create a notification, and then remove it, just to access App notifications is impractical and would never work. Desired Outcome: I'm looking for a way to bypass this prerequisite and force the Apps section to appear in the Notifications and activity section without any user action whenever an app is pinned in the Teams admin center with a setup policy. I'm hoping this can work with any app, not just Viva Engage. Any help is appreciated. Thanks, Teams experts! -Rob
