How to set up Zoom and Microsoft Teams interop

Zoom and Microsoft Teams interop lets users on either platform join meetings on the other without switching apps. When a Zoom meeting link is shared in a Teams channel, Teams users see a “Join” button and can participate directly from the Teams client. Video, audio, and screen sharing all work across the bridge.

This is essential for organizations running both platforms — external partners on Teams can join your Zoom meetings without installing Zoom, and your Zoom users can join Teams meetings without switching clients.

What Interop Does

When a Teams user joins a Zoom meeting:

1. Someone shares a Zoom meeting link in a Teams channel or chat.
2. Teams recognizes the Zoom link and displays a “Join” button.
3. The Teams user clicks “Join” — the meeting opens within the Teams client.
4. Audio, video, and screen sharing work through the interop bridge.
5. The Teams user appears as a participant in the Zoom meeting.

When a Zoom user joins a Teams meeting (via CVI):

1. A Teams meeting includes CVI (Cloud Video Interop) dial-in coordinates.
2. The Zoom user dials the CVI address from Zoom or a Zoom Room.
3. The interop bridge connects them to the Teams meeting.
4. Audio, video, and screen sharing work through the bridge.

What works across the bridge:

Prerequisites

• Zoom paid plan (Pro, Business, or Enterprise)
• Zoom admin access to enable the Teams integration
• Teams admin access to allow external meeting joins
• No additional licenses or add-ons required

Step 1: Enable Interop in Zoom

1. Sign in to the Zoom web portal as an admin.
2. Go to Settings > Meeting > In Meeting (Advanced).
3. Find Microsoft Teams integration and toggle it On.
4. Click Save.

If you don’t see this setting, check that your Zoom plan supports it (Business or Enterprise). Some older Pro plans may not include the Teams interop feature.

Step 2: Configure Teams to Allow External Meeting Joins

1. Sign in to the Teams admin center.
2. Go to Meetings > Meeting settings.
3. Under Participants:
   • Set Anonymous users can join a meeting to On.
   • This allows non-Teams users (including Zoom interop connections) to join Teams meetings.
4. Go to External access:
   • Verify that external communication is not blocked for the domains your Zoom users are on.
   • If you use domain-level controls, ensure Zoom’s interop domains are allowed.

For Teams Users Joining Zoom Meetings

No additional Teams configuration is needed. When a Zoom link is shared in Teams, the interop is handled automatically by the Zoom service. Teams recognizes the link and provides the “Join” button.

Step 3: Test the Interop

Test: Teams User Joining a Zoom Meeting

1. Create a Zoom meeting and copy the join link.
2. Share the link in a Microsoft Teams channel or chat.
3. From a Teams client, click the “Join” button.
4. Verify:
   • Audio and video connect from the Teams client
   • The Teams user appears as a participant in the Zoom meeting
   • Screen sharing works in both directions
   • Chat messages are visible to both sides

Test: Zoom User Joining a Teams Meeting (Requires CVI)

1. Create a Teams meeting that includes CVI dial-in coordinates.
2. From a Zoom Room or Zoom client, dial the CVI address.
3. Verify:
   • The connection establishes through the interop bridge
   • Audio and video work
   • Screen sharing works

Zoom Rooms Direct Guest Join

Zoom Rooms has a special capability: Direct Guest Join for Teams meetings. This lets a Zoom Room join a Teams meeting without a CVI provider.

1. In the Zoom admin portal, go to Room Management > Zoom Rooms > Account Settings.
2. Enable Join third-party meetings > Microsoft Teams.
3. When a Teams meeting appears on the Zoom Room’s calendar (via Exchange integration), the room displays a “Join” button.
4. Tapping “Join” connects the Zoom Room directly to the Teams meeting.

This is the simplest way to get Zoom Rooms into Teams meetings — no CVI license needed.

What Users Need to Know

Send this to your users after enabling interop:

For Teams users joining Zoom meetings:

• When someone shares a Zoom link in Teams, click the “Join” button in the chat.
• You don’t need a Zoom account or the Zoom app.
• Audio, video, and screen sharing work normally.
• Some Zoom features (breakout rooms, polls, reactions) won’t be available to you.

For Zoom users joining Teams meetings:

• If the meeting includes CVI dial-in info, you can join from Zoom.
• Otherwise, join the Teams meeting from a browser at teams.microsoft.com (no Teams install needed).
• Zoom Rooms can join Teams meetings directly if enabled by your admin.

Common Issues

• Teams doesn’t show a “Join” button for Zoom links — The Zoom link must be a valid Zoom meeting link (not a Zoom Webinar or Zoom Events link). Also verify that Teams’ external access settings aren’t blocking the Zoom domain. Clear the Teams cache if the button doesn’t appear.
• Audio echo or feedback during interop — The transcoding bridge can occasionally cause echo. Ensure participants are using headphones or have echo cancellation enabled. If one participant is on both platforms simultaneously (e.g., Teams and Zoom open), mute one.
• Video quality is lower than expected — Interop bridges typically limit video to 720p. This is a limitation of the transcoding layer, not a configuration issue. For the best video quality, participants should use the native platform (Zoom for Zoom meetings, Teams for Teams meetings).
• “Meeting not found” when Teams user tries to join — The Zoom meeting may have ended, the meeting ID may be wrong, or the meeting requires registration (which interop doesn’t support). Verify the meeting is active and doesn’t require Zoom-specific authentication to join.
• Interop setting not visible in Zoom admin — This feature requires a Zoom Business or Enterprise plan. If you’re on a Pro plan, contact Zoom sales about enabling the Teams interop add-on.
• Recording not working — Recording must be initiated from the host platform. If it’s a Zoom meeting, the Zoom host must start recording. Teams users joining via interop cannot start recording from the Teams side.
• Chat messages not syncing — Basic text chat works across the bridge, but rich content (files, images, reactions, threads) does not sync. Keep chat communication simple during interop meetings.
