In this step-by-step tutorial, learn all about how to use tags in Microsoft Teams. Tags in Microsoft Teams let users communicate with a subset of people on a team. Tags can be added to one or multiple team members to easily connect with the right subset of people. Team owners and members (if the feature is enabled for them) can add one or more tags to a person. The tags can then be used in @mentions by anyone on the team in a channel post or to start a conversation with only those people who are assigned that tag.
