In a Microsoft Teams Blog post, Microsoft described the scenario directly. Your team wants to use the room's audio, video and displays, present, and follow the conversation, and the company says you shouldn't have to give up your room's setup just because the meeting is on another platform. The name for the joint effort is Cross-Platform Meeting Connect.
One point matters more than any other for IT admins: this is a roadmap announcement, not a release. Microsoft gave no ship date, rollout schedule, list of supported devices or minimum software versions. Hold off on rewriting the room-booking FAQ for now.
What Microsoft and Zoom announced
The work builds on something both companies already do. Microsoft says Direct Guest Join will allow Teams Rooms to join Zoom Meetings and Zoom Rooms to join Teams meetings. According to the post, Microsoft and Zoom are building on that foundation with Cross-Platform Meeting Connect, to address some of the most requested needs of people joining meetings from a conference room, regardless of the platform they use.
The broad goal: planned improvements to sharing, meeting visibility, room controls, and HD video are designed to help people contribute confidently using the room's capabilities.
Here are the planned features:
- HDMI sharing: With planned HDMI sharing, people will be able to connect a laptop to the room and share content directly into the meeting. The room will also show content that other participants share.
- Participant roster: A list of participants on the room display that updates as people join and leave. This helps with attendees who aren't visible in the current video layout.
- Read-only chat: Chat from the meeting platform appears next to the video, and people in the room can show or hide the panel. Microsoft is clear that it's read-only. You can read messages from the room but you can't type or send them.
- Synced room controls: Room hardware and the touch console stay in sync with the hosted meeting. The first delivery focuses on mute, unmute and end-call.
- Two-display layout: In rooms with two screens, shared content goes on one and the participant gallery on the other.
- Video up to 1080p: Microsoft says sending and receiving at up to 1080p is supported for a Teams meeting on Zoom Rooms. Actual resolution depends on the meeting platform's policies, the room hardware and network conditions. Quality drops automatically when bandwidth or hardware can't keep up, because staying connected comes first.
Section summary: The six features target the most common complaints about cross-platform room meetings: you can't present from the table, you can't see who's on the call, you miss the chat, the mute button can't be trusted, the second screen sits unused, and the video is soft.
Why these features matter: what Teams Rooms can't do today
The feature list makes more sense next to Microsoft's current documentation for third-party meetings on Teams Rooms, last updated September 28, 2026. That Microsoft Learn page says Teams Rooms can connect to other platforms in two ways:
- Direct Guest Join (DGJ): a WebRTC, browser-based connection. The room connects straight to the third-party platform's website.
- Cross-platform meetings via SIP: a SIP video connection, which needs a paid SIP dialing plan.
Microsoft's comparison table shows big differences between the two:
| Capability (current Teams Rooms docs) | SIP join | Direct Guest Join |
|---|---|---|
| Send/receive video | Up to 1080p / 30 fps | Up to 720p / 30 fps |
| Receive content | Available | Available |
| Send content with HDMI | Available | Not available |
| Max front-of-room displays | Two | One |
| Microphone mute sync | Not available | Not available |
| SIP paid dialing plan required | Yes | No |
| Direct internet access required | No | Yes |
| Teams Rooms license | Pro | Basic or Pro |
Set the announcement next to that table and nearly every feature lines up with a "Not available" or a lower limit on the DGJ side. HDMI sharing is listed as not available for DGJ today. DGJ supports one display, and the planned layout uses two. DGJ tops out at 720p, and the plan mentions 1080p. Microphone mute sync is marked not available for both join methods, which shows why synced mute was picked as the first control to fix.
That comparison is our reading of Microsoft's own documents. Microsoft hasn't published it as a mapping, and the announcement doesn't say these Learn limits will change on any particular date or for any particular configuration. The 1080p claim, for example, is worded specifically for Teams meetings on Zoom Rooms. Don't read it as a promise that Teams Rooms joining Zoom will get the same resolution.
Microsoft's table also marks participant lists, chat viewing and layout controls with an asterisk on both paths. The note explains that third-party features were available when the page was last updated, may vary by platform, and can change when other providers change their support. The new work seems aimed at making those features more consistent instead of best-effort.
Section summary: Today, DGJ is the cheap, easy option with notable gaps, and SIP fills more of them but costs more. Cross-Platform Meeting Connect looks like an attempt to give guest joins more SIP-like features. No timeline has been confirmed.
Zoom's side of the bridge
The effort really does run both ways. Zoom's own documentation says the Zoom Rooms and Teams Rooms interoperability allows Zoom Rooms to join Microsoft Teams meetings using a web-client–based join approach (and vice versa), enabling organizations to maintain Zoom Rooms as their standard conference room platform while still supporting Teams-hosted meetings from shared meeting spaces. Zoom describes the problem the same way Microsoft does: room platforms are often standardized, while meeting platforms vary by audience.
That's the honest case for the partnership. Neither company is going to win every meeting invite, and a room that handles the other platform poorly is a room people stop booking.
The fine print Microsoft put up front
The announcement is unusually direct about its limits. Microsoft says a guest meeting will still differ from a native meeting, and that the work won't bring every enhancement to every platform. Each capability depends on support from both the room system and the meeting platform. Microsoft frames this as making sure people see controls that actually work in their meeting.
In practice, expect the feature set to differ by direction, room OS, and possibly device. Even after the roll-out, a Zoom meeting in a Teams Room won't behave exactly like a Teams meeting in a Teams Room. Chat being read-only is a clear example of where Microsoft has drawn that line.
What admins can do now
None of the new features need action yet. However, Cross-Platform Meeting Connect builds on Direct Guest Join, so rooms with a working DGJ setup are best placed to pick up the improvements when they arrive. Microsoft's current Learn guidance lists these steps:
- Pick a join method. Use DGJ for simplicity, or SIP if you need today's HDMI sharing, dual screens and 1080p, and can pay for a dialing plan. Microsoft notes that rooms with SIP enabled use SIP by default and fall back to DGJ from the calendar join button if the invite has no SIP dial string. Join-by-ID with no SIP capability will fail.
- Let the room mailbox process external invites. In Exchange Online PowerShell, run
Set-CalendarProcessing <UserPrincipalName> -ProcessExternalMeetingMessages $True -DeleteComments $Falseso the room accepts forwarded invites and keeps the invite body, which it needs to build a join button. - Protect join links from URL rewriting. Microsoft says Defender for Office 365 Safe Links needs no extra steps. Third-party URL scanners may rewrite join links, though, so add trusted entries such as
*.zoom.us/*,*.zoom.com/*and*.zoomgov.com/*to their exception lists. - Open the network path for DGJ. The room connects directly to the provider's site, so firewalls and web filters must allow that traffic without authentication. Check the provider's documentation for the exact URLs and IPs.
- Turn on the provider. In the Teams Rooms Pro Management Portal, go to Rooms, choose the room, then Settings, then Meetings, toggle Zoom and select Apply. You can also do this locally from the device's admin settings.
On licensing, Microsoft's Teams Rooms licensing page currently lists DGJ for Zoom and Webex under both Teams Rooms Basic and Pro. That covers today's DGJ only. Microsoft hasn't said which license each future Cross-Platform Meeting Connect feature will need. Since dual-screen support is a Pro feature in native Teams meetings, it wouldn't be surprising if the two-display layout followed the same rule, but that's speculation and not confirmed.
The bottom line
Cross-Platform Meeting Connect is mostly a list of fixes for the problems people hit most often in cross-platform room meetings: presenting over HDMI, seeing the roster and chat, trusting the mute button, using both screens, and getting sharper video where the hardware and network allow. Microsoft's own docs still list several of these as missing for Direct Guest Join today, which is why the announcement is worth paying attention to.
Until features start showing up in release notes for specific devices, treat this as a direction of travel and not a deployment plan. Get your DGJ setup working, keep your end users' expectations realistic, and see whether these features arrive for both Teams and Zoom rooms or only one.
