Additional meeting and call-related features and issues within Microsoft Teams for business
Hi James,
My name is Didi. I'm happy to help you today.
It may be different from Discord, but currently, we can hold down the Ctrl+Spacebar (Windows) and Option+Spacebar (Mac) to quickly unmute. And release keys to go back to muted state again.
We can enable this from Settings > Privacy > toggle on 'Keyboard shortcut to unmute'
You may see the link for more information regarding this setting:
