Microsoft Teams Limit

Microsoft Teams has gathered quite a large corporate user base. Its seamless integration with other Microsoft products like PowerPoint, Planner, and more, have made it a go-to as a collaboration tool. But what limits does the video conferencing app have? Here is everything you need to know about.

What is Microsoft Teams

Microsoft Teams is the tech giant’s foray into the world of video conferencing. Teams stands apart in the sea of video conferencing apps with its unique ‘Channel’ feature that lets you build subgroups under the original ‘Team’.

Microsoft Teams is equipped with audio and video calling capabilities as you would expect from an app in the genre. However, what makes the app a perfect collaboration tool is its integration with other Microsoft products. Teams allows users to share and edit documents right within the app itself. It also has a cloud sync feature that lets you keep your documents available for download whenever necessary!
