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!Apps notification settings missing in Teams settings
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! -RobFrom Threads to Workflows: Microsoft Teams Features That Boost Everyone’s Productivity
Organizations are looking to achieve more—and need tools that help them work faster, simpler, and smarter. Guided by customer feedback, Microsoft Teams continues to evolve. Earlier this year, we launched the new chat and channels experience: a unified, streamlined interface that brings simplicity by default, with powerful capabilities just a click away. We’re introducing the next wave of innovations in Teams, with features like threads, multiple emoji reactions, and emoji-triggered workflows. These updates help make collaboration more open and organized, bringing together people and, increasingly, AI agents. They also boost personal productivity by automating routine tasks and enabling you to adapt Teams to your work style. Threads in channels, something many users will be familiar with, are a key part of this evolution. It combines the simplicity of chat-like conversations with the structure, durability, and manageability of channels—helping you stay on top of the information that matters most without getting overwhelmed. Let’s take a look. Enhance group collaboration Efficient collaboration moves work forward—and seamless communication is key. Teams need to share knowledge, brainstorm ideas, and resolve challenges quickly. But in today’s fast-paced, always-on-work environment, the workday can feel like a blur. The Work Trend Index calls this the “infinite workday”—where the workday is stretched and attention is constantly under pressure. To help with this challenge, we’re introducing threads in channels—to make collaboration more efficient and focused. With threads, you can reply directly to specific messages, keeping related conversations grouped together without disrupting the main flow. This preserves context and order, making it easier to stay up to date, while allowing for in-depth discussions. You can follow the threads that matter most to you, and when an important update or decision is made, you can send it back to the main conversation, so everyone stays aligned without requiring them to sift through every reply. The Followed Threads view brings all your followed conversations into one interactive list. You can quickly access all your threads, triage and respond—without jumping between channels. And when you're done with a thread, unfollow it to stop receiving future updates. By default, you’ll only follow threads you’ve started, replied to, been mentioned in, or explicitly chosen to follow. ‘Follow’ helps you stay engaged with key conversations, without unnecessary interruptions. The new threads layout complements the existing post layout. While posts are ideal for announcements and broad updates, threads are a better fit with dynamic, scaled collaboration. When creating a new channel, select between threads or posts layout, and don’t worry, this can be changed later without loss of fidelity. By setting up dedicated channels for each project, you can keep stakeholders, files, and updates all in one place—making teamwork more connected, transparent, and efficient. Apps are supported in the threads layout. Bots can start new threads, read messages and respond within a thread, just like a teammate. Channel meetings and ‘meet now’ are supported too, with each meeting getting its own thread to keep content grouped together and easy to find. Threads in channels are now in public preview. Your work isn't limited to just a desktop, so we will bring threads in channels to all devices for seamless productivity, including desktop, mobile, iOS, and Android. Threads in channels is now in public preview. Threads help you keep context while reducing clutter, and emojis help build meaningful connection. In a hybrid workforce, being able to express yourself on Teams helps strengthen team culture. You can now react with multiple reactions per message, enhancing your ability to express a wide range of emotions effectively. For example, react with✅ and 🙏 to convey appreciation and alignment without extra replies. And with custom emojis, introduced last year, your team can reflect its unique identity, from inside jokes to branded visuals, making interactions more personal and fun. Multiple emojis per message is now in public preview. Boost personal productivity Staying productive and meeting deadlines is critical. With the right tools, you can spend less time on repetitive tasks and more time driving impact. These new features let you tailor Teams to your needs, helping you make meaningful progress where it counts. You can now trigger workflows with emojis by reacting to messages in a chat or channel—streamlining tasks, reducing manual follow-ups, and speeding up responses. For example, reacting with ❗️can escalate a support issue by creating a helpdesk ticket, while 👀 can forward a message to the right channel. This helps ensure urgent items are addressed quickly and without a manual follow-up. Use emojis to automate DevOps, incident response, team collaboration, and more with the Workflows app. This is now available in public preview. Slash commands in Teams are getting more powerful. With support for multi-step inputs, you can now complete more complex tasks—like searching for a GIF, or jumping directly to a channel using /goto—without ever leaving your chat. These enhancements help you move faster and stay in the flow. Slash commands enhancements are now in public preview. Customize your keyboard shortcuts in Teams to work the way that’s most intuitive to you. Whether you're used to shortcuts from other tools or have your own workflow preferences, you can now set commands that match your habits—helping you work efficiently. To set it, open Keyboard shortcuts from the top bar menu (•••), and enter your own custom commands. Customize your keyboard shortcut is available in public preview. What’s next These latest Teams updates help you spend less time managing work and more time making progress. By cutting distractions, streamlining communication, and automating tasks, we’re helping you reclaim focus in a world where the workday often feels infinite. Teams enables people and agents to work together through secure, collaborative AI — from Copilot integration to agents created with Teams AI library, Copilot Studio, SharePoint, and more. The new threads layout helps bring together the right mix of people and agents for every step of the project, while keeping discussions focused and organized. We recently announced Model Context Protocol (MCP) and Agent to Agent Communication (A2A) support which allows developers to build more comprehensive agents that can talk to one another. These updates are just the beginning of enhancing human and agent interaction in Teams and there’s much more to come. Ready to try it out? Visit Microsoft adoption to learn more, or head to the Teams app to start using these features in public preview today.
