Like any tool, however, it can also become a distraction. Meetings with multiple members, for example, can quickly get out of control as everyone rushes to speak at once. And if you have disruptive people in the chat, it can get even worse. Luckily, you can block or mute people to maintain some semblance of order.

There are three types of accounts - organizational, educational, and personal with slightly different functionality. You can block a user only if you are accessing MS Teams from a personal account. If the person is part of your organization, you might want to just mute them if it is a minor irritation or report them to your system administrator or HR if it is a serious problem. 

  1. In MS Teams, click the message of the person you want to block or mute. 
  2. Click the menu (three dots) icon that now appears to open the menu. 
  3. In the drop-down menu, click Block.
  4. If Block is not available in the menu, click Mute in the drop-down menu instead.
