Zoom Interop for Microsoft Teams allows Zoom Rooms to join Microsoft Teams meetings without the need for additional infrastructure or licensing. Connecting to Microsoft Teams meetings previously required the Teams meeting host to be entitled to Microsoft Cloud Video Interop third-party services.

How to enable or disable third-party conferencing dial-in for Zoom Rooms

1. Sign in to the Zoom web portal as an admin with the privilege to edit Zoom Rooms settings.
2. In the navigation menu, click Room Management then Zoom Rooms.
3. Use the Zoom Rooms location hierarchy to enable third-party conferencing dial-in for Zoom Rooms from the account, location, or room settings. For this example, click Account Settings.
4. Click the Meeting tab.
5. Under Zoom Rooms, click the Support Interoperability for Zoom Rooms toggle to enable or disable it.
6. If a verification dialog displays, click Enable or Disable to verify the change.
7. (Optional) If you want to make this setting mandatory for all Zoom Rooms you are editing, click the lock icon , and then click Lock to confirm.
8. Click the Support Microsoft Teams web client meeting on Zoom Rooms checkbox to enable Microsoft Teams Direct Guest Join.
9. (Optional) at the individual Zoom Room level, you may set the Guest Name and Email that will represent the Zoom Room in the Microsoft Teams meeting participant list.
10. (Optional) Click the Show on home screen checkbox to display a Microsoft Teams join button on the room controller or touch display. 

11.  (Optional) Under Connection method prioritization, click the up or down arrows next to the option you want to change.
    Note: If you prioritize the Dial SIP option, but no Microsoft Teams Cloud Video Interop (CVI) information is present for the meeting, Direct Guest Join will be used as a backup. 

How to join a Microsoft Teams meeting from a Zoom Room

1. Invite a Zoom Room to a Microsoft Teams meeting by directly adding the calendar resource associated with the Zoom Room to the Teams invite or forwarding a Teams calendar invitation received from a third party to the calendar resource associated with the Zoom Room. Alternatively, a user may cut and paste the entire body of a meeting invitation received from an external third party to a new meeting invite that includes the Zoom Room’s calendar resource.
   Once the calendar resource receives the meeting invite, the Zoom Room will display the meeting on its upcoming meeting list with a Join option on the Zoom Rooms controller. If you see Join by Audio instead, double-check the steps above or see the Troubleshooting section.
   Note: Forwarding the invite may require modification of settings in Microsoft Office 365 or Exchange.  In Google Calendar, forwarding is not possible, but a user with appropriate permissions may add the appropriate room or duplicate the meeting to a room calendar.
2. Click Join on the controller. The Zoom Room will connect to the Teams meeting.
   Note: The join process will take longer than joining a Zoom meeting.
3. After joining, the following in-meeting controls are available: 
   • Mute Microphone
   • Start/Stop Video
   • Volume
   • Leave meeting  
   • Send problem report
   • Rejoin meeting
   • Share content
   • Rooms controls (if configured)

   • Camera controls (if only one camera is connected to the system; camera controls are not available if multiple cameras are present)

Zoom Interop for Microsoft Teams is only supported in Zoom Rooms with a single camera, single microphone and single speaker. If the Zoom Room has multiple cameras, microphones and/or speakers Microsoft Teams may select the wrong camera, microphone or speaker to use, respectively, and this cannot be changed during the call due to Zoom Interop limitations. The Microsoft Teams meeting will only appear on the first display of the Zoom Room. A second or third display will not show additional Microsoft Teams meeting participants or shared content.

Note: Screen sharing to a Microsoft Teams meeting requires access to the Microsoft Teams client. No wireless or wired HDMI screen sharing is available through the Zoom Room while joined to a Microsoft Teams call using Zoom Interop. Do not connect devices (e.g. a laptop) to the wired HDMI input of a Zoom Room before or during a Microsoft Teams call using Zoom Interop - it may lead to unpredictable results.

Microsoft Teams Direct Guest Join user interface changes (December 2023)

As part of new Microsoft Teams app updates, Microsoft began to release a new user interface (UI) for Direct Guest Join on December 5, 2023, and plans to complete this update for all meeting attendees by December 15th, 2023. Zoom Rooms using Direct Guest Join to attend Microsoft Teams meetings will see this new UI as it is rolled out over this period. The user interface changes are primarily cosmetic in nature, such as changes to the color palette (e.g. the background color) and in-meeting video layout, along with a faster overall meeting join experience. In-meeting capabilities are essentially unchanged, though Microsoft has reduced the touch interface controls to those appropriate to a conference room device.

Note: Zoom Rooms attending a Microsoft Teams meeting open a Microsoft-provided browser-based meeting experience, similar to attending a MS Teams meeting from a desktop browser. The Teams meeting experience is developed and maintained by Microsoft.

Troubleshooting Zoom Interop for Microsoft Teams in Zoom Rooms

If you see Join by Audio or no Join button at all on the Zoom Rooms controller meeting list

1. Ensure that Support Interoperability for Zoom Rooms and Support Microsoft Teams web client meeting on Zoom Rooms are enabled for the Zoom Room.
2. If you are using Office 365 or Microsoft Exchange for your Zoom Rooms calendar integration, ensure that the "deletecomments" automated calendar processing option is set to "False" and "ProcessExternalMeetingMessages" is set to "True" in your Office 365 settings. For example:
   Set-CalendarProcessing -Identity calendar@accordion.com -AddOrganizerToSubject $false -OrganizerInfo $true -DeleteComments $false -DeleteSubject $false -RemovePrivateProperty $false -ProcessExternalMeetingMessages $True
3. Users leveraging link filtering or “safe links” services that rewrite the original Microsoft Teams meeting URL will not be able to use Zoom Interop.  The original link must be preserved in order  for a Join button to appear in Zoom Rooms. Customers using Proofpoint URL Defense can safelist the teams.microsoft.com URL following the instructions here.  Customers using similar URL “safe links” services must safelist the teams.microsoft.com URL.
4. Make sure the Teams URL contains teams.microsoft.com, not teams.live.com or other domain.  The Zoom Interop for Microsoft Teams feature only supports  meetings hosted on teams.microsoft.com.
5. If the Teams meeting was initially received from an external third party, copy and paste the entire Teams meeting invite into the body of a new meeting invite that includes the calendar resource associated with the Zoom Room.

If you see the Join button on the Zoom Rooms Controller

• If it appears as though the Zoom Room attempts to Join the Teams meeting but fails, there may be firewall or other network security issues interfering with the connection to the Teams cloud server. Please check that your firewall implements the Microsoft Teams firewall requirements. Include the Office 365 URLs and IP address ranges, particularly the ranges for Skype for Business Online and Microsoft Teams, and Microsoft 365 Common and Office Online.

• The Microsoft Teams meeting host must permit guest access for Meetings. This setting may be checked and, if necessary, changed by an administrator of the meeting host’s Microsoft Teams services. Please check here for more information on Microsoft Teams guest access.
• The Microsoft Teams meeting host may have configured the meeting to require that guests, such as a Zoom Room using Zoom Interop, be admitted from the Microsoft Teams meeting lobby. If this is the case, the host or possibly another authenticated user must admit the Zoom Room to the Microsoft Teams meeting. Please check here for more information on Microsoft Teams and automatic admission to meetings.

If you have joined the Microsoft Teams meeting

• If you are using a Zoom Room with Zoom Rooms for Touch capability to join the Microsoft Teams meeting, Zoom recommends controlling the meeting experience (e.g. volume, mute, etc) from a Zoom Rooms Controller.  Though the touch UI will allow manipulation of the Microsoft Teams meeting controls on the Zoom Rooms display, use of the touch UI is not supported for this function.
• Microsoft Teams meetings use "simulcast" from the sender-side to offer multiple video resolutions to Teams meeting clients, including Zoom Rooms using Zoom Interop. Depending on network bandwidth and the resolution requests of other Teams meeting clients in the same meeting, the resolution sent and received by a Zoom Room using Zoom Interop may vary. If all Teams meeting clients can support high resolution streams, a Zoom Room will receive a high resolution video stream from Microsoft Teams, whilst the presence of low resolution receivers will force a Zoom Room to receive a lower resolution.
• Microsoft Teams web client code supports a maximum gallery view layout of 2x2, even if >4 participants are in the meeting.
• In the event a Zoom Room is experiencing other issues with a Microsoft Teams meeting, you can send a problem report to Microsoft:
  1. Join a Teams meeting from the Zoom Room.
  2. Tap the ellipses icon icon at the top right, then tap Send Problem Report.
  3. Fill in the information, ensure that the Send Information to Microsoft box icon is checked, then tap Send.
