May’s update is a security-heavy one on the calling side, brand impersonation protection and suspicious call reporting are both worth rolling out deliberately rather than just letting them land. Add Queues on mobile, a genuinely useful video recap feature, and Teams Rooms getting smarter about fixing itself overnight, and this is a solid month for anyone running Teams at scale.
Microsoft Teams Phone
- Brand Impersonation Protection. Teams now detects in real time when an incoming caller may be impersonating a trusted brand, your IT helpdesk, your bank, or Microsoft Support, and shows a “Scam suspected” identity signal live on the call, before you engage. You can decline, leave, or report the call instantly. No extra tooling required, it’s built into the calling experience. Rolling out, worldwide (Standard Multi-Tenant, GCC).
- Report a Suspicious Call. Users can flag unusual or suspicious calls directly from the Calls app history, select “Report call,” add a reason, and optionally block the caller. Reported signals feed Microsoft’s detection systems, so it’s a small action with a collective payoff for org-wide call security. Launched.
- Queues app for Teams Mobile. The Queues app, advanced queue management and collaborative calling, now works on Teams mobile. Built for people who can’t sit at a desk all day (bank tellers, IT help-desk reps): stay opted into a queue, review recent calls, and return missed customer calls from a phone. Rolling out.
- Consult and merge a PSTN caller through DTMF. Meeting organizers can now privately consult a PSTN expert and merge them into an active Teams meeting, even when reaching that person means navigating a DTMF auto-attendant phone menu first. Useful for pulling in a subject-matter expert who sits behind a phone tree. Launched.
Between Brand Impersonation Protection and Report a Suspicious Call, this month is a genuine step forward against vishing-style attacks that impersonate helpdesk or Microsoft Support calls. If you run security awareness training, add these two features to it, end users reporting calls is only useful if they know the option exists.
Teams Meetings, Webinars & Town Halls
- Video recap. Turns a recorded Teams meeting into a short, AI-narrated highlight reel, an AI-generated voiceover paired with real clips of key moments, decisions, and shared visuals. Available to Microsoft 365 Copilot–licensed users on Teams for Windows, Mac, and web. Works on recorded, English-language meetings between 10 and 90 minutes. Launched.
- Ability to delete recap. Organizers can now delete a meeting’s recording, transcript, AI summary, and notes from one place, the recap page’s “More” menu, instead of removing them separately or asking an admin. Files shared during the meeting stay in their original location. A real quality-of-life fix for data retention practices. Rolling out.
- Bot Detection (Teams admin policy). A new tenant-wide admin policy controls how automated participants (bots) are handled when they try to join meetings. Organizers see bots clearly flagged in the lobby and make an intentional decision to admit or deny them. Rolling out.
Workplace: Microsoft Places and Teams Rooms
- Enhanced media quality for Direct Guest Join (Windows). Direct Guest Join, joining from Zoom, Google Meet, or Cisco devices, now supports up to a 4×4 grid (16 participant videos), up from a smaller gallery. Simulcast streaming for more reliable cross-platform video arrives in June. Rolling out.
- Miracast support for Teams Rooms on Windows touch boards. All-in-one touch boards now support cable-free Miracast screen mirroring alongside Teams Cast and HDMI ingest, walk in, mirror your screen, present. Ideal for flex spaces with guests. Requires Teams Rooms Pro. Rolling out.
- Multi-camera view support for GCC-H and DoD. Remote participants in Teams Rooms on Windows can now switch between multiple in-room camera feeds, a meaningful visibility improvement for larger rooms where one fixed angle isn’t enough. Requires Teams Rooms Pro. Launched.
- Multi-stream IntelliFrame support for GCC-H and DoD. Sends a separate video feed of each in-room participant instead of one wide shot, so remote attendees can actually read faces. Needs a compatible intelligent camera and Teams Rooms Pro. Launched.
- Book future meetings directly from Teams panels. Reserve any open time slot through midnight the next day straight from a Teams panel, with the option to add a guest during booking. Available with Teams Rooms Pro and Shared Device licenses. Rolling out.
- Enhanced issue detection and auto-remediation (Teams Rooms Pro Management). Teams Rooms on Windows now proactively monitors room audio, video, and display signals, and Pro Management auto-resolves common software, configuration, or device-reset issues during nightly maintenance. This is the feature IT admins running large room estates should pay attention to, fewer morning “the room is broken” tickets. Rolling out, Teams Rooms Pro–licensed rooms only.
- Room health signals and notifications. When critical issues impact room functionality, a banner notification now shows on both the front-of-room display and the console, so problems get resolved before they derail a meeting. Requires Teams Rooms Pro. Rolling out.
- Expanded AI Assistant access in Pro Management. The AI Assistant in Teams Rooms Pro Management is no longer limited to global admin roles, role-based access controls (RBAC) now let room and meeting-room admins use it too, scoped to the rooms and devices they actually manage. Generally available.
Certified for Teams devices
- Barco ClickShare Hub Core with Logitech MeetUp 2, small-room bundle with one-click wireless sharing (Wi-Fi 6E, USB-C DisplayPort) and AI-enhanced USB audio/video from the MeetUp 2.
- Jabra Scheduler, a professional room-scheduling panel with an integrated lightbar and touchscreen for at-a-glance availability.
- Neat Pad Pro, dual-role device: meeting-room controller or scheduling display, with a 10-inch touchscreen and built-in microphones.
- Jabra Speak2 40, USB speakerphone with true full-duplex audio, four beamforming mics, and both USB-C and USB-A connectivity on the same cable.
- Owl Labs Meeting Owl 5 Pro, all-in-one 360° centre-of-table camera, speaker, and mic with 4K video, automatic speaker switching, and native HDMI/Ethernet for single-cable BYOD setups; also works with Zoom and other platforms.
Teams device software updates
- Teams Rooms on Android, 1449/1.0.96.2026100103 (May 2026): fixes an issue that prevented Teams Rooms on Android from joining Teams webinars, restoring the webinar-join experience.
- Teams Rooms on Windows, 5.6.135.0 (May 27, 2026): adds Miracast for all-in-one touch boards, non-dismissible room health banner notifications, and the enhanced issue detection/auto-remediation described above. Also enforces a default front-of-room resolution and scaling factor for consistent screen elements (1920x1080 defaults to 100% scaling, 3840x2160 to 200%), note: going forward, resolution and scaling should only be configured via the Pro Management Portal or XML, not overridden ad hoc. Fixes: Whiteboard meeting audio/video settings not applying correctly under Coordinated meeting join, and the touch console freezing after entering/leaving a breakout room.
- Teams panels, 1449/1.0.97.2026164101 (May 2026): adds the ability to book future meetings directly from the panel (detailed above; guest-booking is off by default and needs admin enablement). Also fixes authentication issues, DM/broker integration, and various UI bugs.
What’s coming next
From the Microsoft 365 Roadmap:
- In development: Queues app for Microsoft Teams in GCC High, automatic recording/transcription for Teams Call Queues, multi-line calling on Teams mobile, a tenant-level dashboard for Interpreter, a redesigned meeting recap app, mandatory pre-meeting consent.
- Rolling out: shared and delegate mailbox scheduling for Teams Events, saving an event as a reusable template.
Why this matters
The security features here, Brand Impersonation Protection and Report a Suspicious Call, deserve active communication to end users, not passive rollout; they only work if people know to look for the warning and use the report option. On the infrastructure side, auto-remediation for Teams Rooms is the one to watch if you manage a large room estate: fewer manual fixes, fewer “meeting room broken” tickets on Monday morning.
