What you need to know

  • Microsoft Teams will soon have an option to temporarily unmute a microphone during a meeting.
  • Pressing CTRL and the spacebar will unmute your microphone when held down.
  • The feature could arrive as soon as October 2021, but that date is subject to change.

Anyone who has accidentally said something during a virtual meeting will appreciate an upcoming feature for Microsoft Teams. A new option within Teams will let people temporarily unmute their microphone by pressing CTRL and the spacebar. Once you let go of these keys, Teams will mute your microphone again. The feature is in development and could arrive as soon as October 2021, but that date could change.

"Introducing the capability to allow meeting participants to temporarily unmute by [pressing] "Ctrl Spacebar" to speak," says the Microsoft 365 roadmap (opens in new tab).

Microsoft Teams already allows people to mute and unmute their microphones by pressing a button within the app. Teams also supports CTRL+SHIFT+M to toggle between mute and unmute. These options switch between a microphone being enabled or disabled. In contrast, the new CTRL+SHIFT option should only turn your microphone on while you hold the keys down.

This setup reduces the risk of accidentally leaving a microphone on during a meeting. It also makes it easy to jump in with a quick comment.

The option to temporarily mute a microphone during a meeting differs from "push-to-talk" (PTT) functionality, which allows Teams to act like a walkie-talkie. PTT support is also in development and could arrive as soon as this month (opens in new tab).

  • This is a good idea... glad to see them borrow this feature from Zoom. Having users in complete control of when their voice is transmitted is a very good idea (like pushing a button on a walkie-talkie to speak).
  • To be honest, users already have that - click the mic icon to mute or inmute... Not sure why people find that difficult... As the mic icon is fairly obvious on a pc, laptop or tablet - that's true for Teams and Zoom. What's not so fairly obvious is on the mobile app when Zoom automatically enables driving mode during long events. Otherwise it's fairly obvious just like Teams on mobile phones. What was really needed was familiarisation training for Zoom and Teams or any other meeting software during the early days of lock downs / before going into the first lock downs etc. But, most people don't think logistically let alone holistically. Most people's concept of logistics is getting from point a to b.
  • How does pushing a key, or key combo, to unmute a mic, and releasing it to re-mute it differ from push-to-talk? PTT is what you want. That's what the mic button on my MS LifeChat LX-4000 headset should do. Should be an option to lock on, PTT should be default.
  • PTT should be enabled by default for meetings with more than 3 people imo.
  • This simple feature shouldn't be difficult to implement, and shouldn't take time. Another reason the Teams app should've been written in UWP.
  • But when will it stop using up a half gig of ram or more?
