Hi my teams microphone is not working , there is no issues with my microphone, i have checked all the settings, everything is configured properly still the issue is occuring pleas ehe

Hello @Mahima Chhablani,  

Thank you for reaching out to the Q&A forum! 

As you've mentioned that all settings appear to be correctly configured, I reviewed the microphone permissions and noticed that Microsoft Teams has been granted access to the microphone, with the last access recorded at 3:30:57 PM on August 20, 2025. 

Other applications also seem to access the microphone normally, which suggests the hardware and system-level permissions are functioning as expected. 

To support you better, you can provide me more information: 

• Are you using a work account (managed by your organization) or a personal account? 
• Does the issue occur in all meetings, or only in specific ones? 
• Have you tested your microphone in other applications, and does it work normally there? 

In meantime, you can try some bellow solutions:  

1. Make a Test Call in Teams: 

Please try using the “Make a test call” feature in Teams: 

• You can go to Settings => Devices => Audio settings 
• Click Make a test call 
• Record a short message and listen to the playback 

If you cannot hear your own voice, this may indicate an issue within Teams itself. 

1. Clear the Teams Cache:  

This forces the Teams client to reload fresh meeting and app data.  

For classic Teams:  

• You need quit Teams completely (right-click the icon in the taskbar => Quit).  
• Press Windows + R to open the Run dialog and then enter: %appdata%\Microsoft\Teams  

• Delete all files and folders inside and restart Teams.  

For new Teams:  

• You need quit Teams completely (right-click the icon in the taskbar => Quit).  
• Press Windows + R to open the Run dialog and then enter: %userprofile%\AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams  

• Delete all files and folders inside and restart Teams.  

Note: You can delete the contents of these folders:  

application cache , blob_storage , Cache , databases , GPUCache , IndexedDB , Local Storage , tmp 

You can infer full instructions on both Windows here: Clear the Teams client cache - Microsoft Teams | Microsoft Learn 

3. Reinstall Teams:  

You can uninstall Teams by going to Settings => Apps => Apps & features => search for Teams => uninstall both Microsoft Teams and Teams Machine-Wide Installer  

Download the latest version from Download Microsoft Teams Desktop and Mobile Apps | Microsoft Teams => log in again to test messaging functionality 

4. Try Teams Web: 

You can visit Chat | Microsoft Teams and join a meeting from your browser. This helps determine if the issue is specific to the desktop app. 

While in the meeting, please check: 

• That you're not muted by the organizer 
• The microphone icon is not crossed out 

Additionally, please ensure that both Microsoft Teams and your Windows operating system are updated to the latest version.  

You should also update your device drivers and check whether the mute mic button was accidentally pressed on your keyboard (for example, on my device, it's mapped to the F4 key)

Hello @Mahima Chhablani,  
Thank you for responding. 

If you're using a work account, I recommend contacting your IT administrator and asking them to help you 2 things: 

1. Teams App Policies: 

It's possible that your organization has applied a policy that affects microphone usage in Teams. You can contact to your IT admin to check following: 

You can go to Teams Admin Center: 

Then, you navigate to: Users => [Your Name] => Policies and review the following policies: 

• App setup policy 
• Meeting policy 
• Calling policy 

These policies may contain settings that block or limit microphone usage in Teams desktop app. 

2. Raise a support ticket: 

If all Teams policies appear normal and the issue still persists, I believe it's time for Microsoft’s higher-tier support to step in. 

Please kindly ask your IT administrator to raise a support ticket via the Microsoft 365 Admin Center: 

• You can go to: Microsoft 365 Admin Center.
• Navigate to: Support => New service request 

For reference: Get support for Microsoft 365 for business.

• In the description, you can use the following sample: 

“Hello, 

The user is experiencing an issue where the microphone does not work in the Microsoft Teams desktop app. 

• The microphone works perfectly in Chrome and other applications 
• All permissions and device settings have been verified 
• The issue occurs in all meetings 
• Cache has been cleared, Teams has been reinstalled, and the latest version is in use 

I request escalate this case with the appropriate technical team for further investigation and resolution." 

Once the ticket opens, a technical support technician can conduct a remote session to investigate the situation, review the backend configurations, and run the necessary synchronization tools to resolve the issue. If further intervention is required, they can refer the matter to a specialized team for in-depth analysis.      

I hope you understand that as a forum moderator, I don’t have access to backend systems to help you directly, but I’ve tried my very best to support you within the limits of my role, and I truly appreciate your cooperation and understanding. 

Please know that I’m genuinely hoping your issue will be resolved as quickly as possible. If you receive any updates, please reply here.

Thank you again for raising this issue; it’s helped broaden my understanding.   

Since many users may not know how to raise a support ticket with Microsoft, if possible, you can consider marking the answer as accepted. This helps others discover not only the troubleshooting steps but also understand the importance of raising a support ticket when basic solutions aren’t enough.
