Microsoft has added two new security features to its Teams roadmap, targeting deepfakes and impersonation in meetings.
-
Third-party tools (not Microsoft itself) will scan meeting audio and video for signs of manipulation.

Both features are in development and are set to roll out worldwide in November 2026.
Microsoft is preparing major security upgrades for its Teams meetings app. The company has added two new features to the Microsoft 365 Roadmap. One targets deepfake audio and video. The other targets impersonation attempts. Both are listed as “In development.” They are scheduled for worldwide release in November 2026.
The move comes as attackers increasingly use video call platforms to trick people. Synthetic audio and video tools now make it easier to impersonate real people during business meetings. Microsoft is responding by building new warnings and detection signals directly into Teams.
Teams will plug into outside Deepfake detection tools
The first feature carries roadmap ID 573451. It will allow Teams to connect with certified third-party tools that detect fake or altered audio and video during live meetings.
Here is an important detail. Microsoft is not building its own deepfake scanner. Instead, outside providers will do the actual analysis. These providers will check the meeting media for signs that the audio or video has been artificially made or changed.
When a provider spots something suspicious, it sends a signal to Teams. Teams then show that information to meeting participants and offer controls to respond.
According to the Microsoft 365 Message Center Archive, the feature will be available on desktop, Mac, and web. It is planned for standard worldwide multi-tenant environments. Microsoft has not yet named which third-party vendors will be supported. It has also not shared what the in-meeting alerts will look like exactly. Those details are expected closer to the November rollout.
This distinction matters. Saying “Microsoft is adding deepfake detection to Teams” would be slightly misleading. A more accurate way to put it is that Teams will support third-party deepfake detection. The outside tool does the detecting. Teams provide the screen where you see and act on the results.
Teams will flag suspicious meeting identities too
The second feature carries roadmap ID 573157. Microsoft is calling it “Impersonation Protection for Teams meetings.”
This tool is built to help users spot fake or suspicious meeting organizers and participants. When Teams detect a possible impersonation attempt, it will show warnings and risk indicators. These signals appear before or during a meeting. They help users decide whether to stay in the meeting or leave. The warnings are meant to catch bad actors who pretend to be someone trustworthy.
According to the Microsoft 365 Message Center Archive, this feature will be available on Teams desktop and Mac. It is also targeting November 2026 for general release.
Microsoft has already been adding identity protections to Teams over the past year. Earlier in 2026, the company introduced Brand Impersonation Protection for Teams calls. That feature warns users about suspicious outside callers who appear to be imitating well-known organizations.
According to BleepingComputer, Microsoft also began letting admins automatically block identified external bots from joining Teams meetings back in August. In addition, Microsoft gave organizations the ability to block outside Teams users through the Defender portal. These moves show a clear and growing effort to lock down Teams against social engineering attacks.
The two new roadmap features extend that same effort into a newer threat area. Deepfake tools have become cheap and widely available. A bad actor can now fake a colleague’s face or voice during a video call. Without detection tools, meeting participants have no easy way to spot the trick.
What Microsoft has and has not confirmed
Microsoft has confirmed the roadmap entries. Both features are in active development. Both are targeting November 2026 for worldwide general availability.
What Microsoft has not confirmed is also worth noting. The company has not named any specific detection vendors for the deepfake integration. It has not shared pricing details or administrator setup requirements.
It has not shown exactly what the warning screens will look like for users. According to the Microsoft 365 Message Center Archive, more details on these points are expected as the release date gets closer. What is clear is the direction Microsoft is heading. Microsoft is also expanding its focus on data privacy and digital sovereignty, including its first Americas Studio in Brazil.
Teams are becoming more than a place to hold meetings. It is becoming a security layer. The platform is now designed to surface threat signals, warn users about risky identities, and give admins tools to block suspicious outside actors.
As synthetic media becomes harder to detect with the naked eye, tools like these will become more important for businesses running sensitive meetings online. Microsoft’s planned November rollout will be a key test of how well these protections work in real-world conditions.
