Disable the unmute shortcut in MM2
In Microsoft Teams , the unmute shortcut can be turned off in the app’s settings. Open Settings > Privacy , then find Keyboard shortcut to unmute and switch it off. Microsoft also documents the mute and unmute shortcut as Ctrl + Shift + M on Windows, while the temporary unmute hold shortcut is Ctrl + Spacebar and can be enabled or disabled in the same privacy area.
If you meant another app called MM2 , the answer depends on which program you’re using, because shortcut controls are different from app to app. In some apps you can remap or remove the shortcut in a keyboard shortcuts menu, while in others there is no built-in way to disable it and you have to use a system- level key remapper instead.
What to try first
- Open the app’s Settings.
- Look for Keyboard shortcuts , Privacy , or Audio.
- Search for an option related to mute , unmute , or temporary unmute.
- Turn that shortcut off if the app allows it.
If the app does not offer a toggle
Some programs do not let you disable the shortcut directly. In those cases, the usual workaround is to remap the key combination so it does nothing, or change the shortcut to something harder to press accidentally.
Important detail
There is no single universal “MM2” shortcut rule that applies to every app, so the exact fix depends on whether you mean Microsoft Teams, Zoom, BlueJeans, or something else. If you are talking about Teams, the privacy setting is the right place to look.
