Microphone in Teams keeps getting muted

This regards an issue while using a professional Teams account of which I am not the admin.

Hi,

Whilst joining a particular Teams session on a regular basis, every 2 days, my microphone keeps getting muted when I try to speak. This topic only applies to that session, it doesn't happen to me elsewhere. Occasionally, this happens even when I don't speak and without any background noise present. It also only happens to me, not anyone else, as well as, it happens also when I am joining via my smartphone.

In terms of settings, updating etc., I have tried everything.

Is there a possibility of reaching out to someone at Microsoft about this who can have a deeper look? I tried reaching out to my company's IT, but they were also rather buffled.

Thank you in advance!

Dear @Bitounis, Spyridon (ECE3D),

Good day! Welcome to Microsoft Q&A forum!

Based on your description, I understand that your microphone keeps getting muted during a specific recurring Microsoft Teams session, even when you try to speak or when there is no background noise. This issue only occurs in that particular meeting, affects only you (even across devices like your smartphone), and persists despite checking settings, updates, and consulting your company’s IT team. You’re looking for further assistance and possibly a way to escalate this to Microsoft for deeper investigation.

Could you help confirm the following:

  • When your microphone gets muted, do you see a message like “You’ve been muted” or “Muted by organizer/presenter”?
  • Does the meeting have a large number of participants (e.g., webinar or lecture-style call)?
  • Have you noticed if someone else (organizer/presenter) might be muting participants manually or via meeting controls?
  • Are you joining using the desktop app, web (browser), or mobile app when this happens or all of them?

Your confirmation would be very helpful in ensuring you receive the most suitable support!

In the meantime, kindly try the following suggestions to check what might have caused the issue:

  • Test across different devices and endpoints: Since you mentioned this also happens on your smartphone, let’s confirm consistency by trying to join the same meeting from: Teams on the web (Edge or Chrome) > https://teams.microsoft.com
  • Test different microphones (important isolation step): This helps determine whether the issue is hardware-related:
    Join the meeting and test using:
    • Your laptop/PC built-in microphone
    • A wired headset
    • A Bluetooth headset (if available)
    • Kindly let me know if the issue persists throughout different microphones
  • Test in a 1:1 meeting (isolation check): To rule out the possibility that someone in the meeting is muting you (intentionally or via meeting controls), try the following:
    • Start a 1:1 Teams call with a colleague or even yourself (via another device/account)
    • Speak and observe whether your microphone gets muted unexpectedly
  • Clear Teams cache: Please refer to this article for step-by-step instructions: Clear the Teams client cache

Kindly let me know when there are updates 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 for your time and patience.

    The described behavior is most likely caused by meeting-specific or organization-level audio settings or policies in that particular recurring session, not by a device issue, since:

    • It only occurs in one specific session.
    • It affects only one participant across multiple devices (PC and smartphone).

    Because this is a professional (work) Teams account and the user is not an admin, deeper investigation must be done by the organization’s IT admin and, if needed, escalated through official support channels. End users cannot directly request Microsoft to inspect a specific meeting; Microsoft support works through the tenant’s administrators.

    Recommended path:

    1. Ask the meeting organizer and IT admin to:
      • Verify if any meeting options, policies, or features (such as automatic muting, specific roles, or moderation features) are configured differently for that recurring session.
      • Check if any custom audio or device policies are applied to the user’s account.
    2. If the issue persists, the IT admin should:
      • Use the Teams troubleshooting resources and admin documentation referenced under “Troubleshoot in Microsoft Teams” to identify known issues.
      • Open a support ticket with Microsoft from the Microsoft 365 admin center or via their standard support channel, providing meeting IDs, times, and logs.

    From the end-user side, standard audio checks (mute state, device selection, test calls, and OS sound settings) are already covered and do not explain a problem isolated to a single recurring meeting.
