Microphone Buttons Disappearing In Breakout Rooms Teams

Tr. Girasol 95

We're having some problems with Teams breakout rooms. Some of the attendees are missing their mics and can't use mics when they join the breakout rooms. It's happening in almost all the meetings. May I know any solutions for this?

I've been having the same problem for several days now. It happens with the latest version of Teams. Every time I'm in breakout rooms, when I return to the main meeting, my microphone also disappears.

We experienced the same issue and found two ways to work around it:

a) Have participants unmute themselves in the main meeting before moving them into breakout rooms. This ensures they can speak to each other once inside.

b) Once in the breakout room, ask them to minimize the screen — the microphone icon should then appear, allowing them to mute or unmute as needed.

Hi everyone,

Thanks for sharing your experiences, it’s clear this microphone issue in breakout rooms is affecting quite a few users across different setups. I’ve seen reports from both desktop and web users, mainly on Windows, and it seems to happen consistently inside breakout rooms, while everything works fine in the main meeting. This looks like a recent issue, possibly tied to a Teams update. It’s not limited to one organization or device type, which suggests it may need investigation from the backend side.

While we wait for more clarity, here are a few things that have helped some users:

Minimize and maximize the Teams window once inside the breakout room this may refresh the UI and bring the mic button back.
Leave and rejoin the breakout room.
Use Teams Web App via https://teams.microsoft.com in Edge or Chrome.
Check breakout room settings: If you’re the organizer, make sure “Participants can unmute themselves” is enabled.
Verify mic permissions in Teams settings: Go to Settings > Devices and confirm the correct mic is selected.

I’re escalating this issue internally so the engineering team can take a closer look. If you’re an IT admin, I recommend submitting a support ticket via the Microsoft 365 Admin Center and checking the Service Health Dashboard for updates.

For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.

I'm truly appreciate your patience and detailed feedback. Your reports are helping us better understand the scope and urgency of this issue. Please continue to share any new findings, and we’ll keep you updated as soon as we have more information from the backend investigation.

In case it helps, my team has been able to consistently get our mute button back if we open the meeting through the breakout room chat directly.

This is happening in our organization as well and it is impacting our ability to deliver virtual trainings due to having to take additional time for the workaround issues. It has impacted our customer experience for the training and has impacted the ability to get through all of our content in the scheduled frame of time. Sometimes the workaround of clicking F4 brings the microphone back, but it doesn't work for everyone. Most people have to drop the meeting completely and sign back in only to have to do this again when sent into another breakout room. Reporting so that you know this is an issue on a grand scale. Thank you.

hi, we have the same issue, we just tried to test it and it is the same for both the host and the attendees if in break out room, once out of the room it works perfectly well. It is all through the browser of Windows users and always every time when logging in. Both the host and the attendee have the updated version of Teams

Hello,

We are a school that is completely on Teams, and we are experiencing this issue at large. first time the issue was reported was Tuesday the 5th.

The problem seems to be isolated to just breakout rooms, once the classes are finished in break out rooms and move back the main meeting the mic button comes back.

Majority of our users are on windows and using the Desktop app. there have been reports of the same happening with web users Aswell.

So far, we have only experienced it with attendees and not the Hosts. All Users have up to date teams and have cleared Cache to no prevail.

Hi @Tr. Girasol

Thank you for contacting Microsoft Q&A Support and for your detailed report.

To understand the situation better, could you confirm the following information:

When did this issue start?
Does it happen in every meeting with breakout rooms or only sometimes?
Are the affected users using Teams on Windows, macOS, mobile app, or web?
Is the host also experiencing the issue, or just the attendees?
Do the affected users have the latest version of Teams?

Your confirmation would be very helpful!

Kindly let me know if these help identify the cause of this issue or if you need further assistance. Any updates you’re able to share would be really helpful. I appreciate your time and look forward to hearing how things are going!

Thank you again for your patience and for choosing Microsoft Q&A forum.

I also noticed this today.

We have 25 participants and someones have issues, but not everybody. I have windows desktop app and Jabra evolve headphones. Opening mic line from headphones bring button back. We had also breakoutrooms in use.

I think there is now some bug in latest update.
