Microsoft Teams was a platform originally designed to facilitate business communication, but later, with the introduction of new features, it was adapted for use in educational institutions. The main features of the Microsoft Teams platform are chats, video meetings and file storage. The main advantage of the platform is that its use is possible without the use of storage on user’s device. It can be accessed from any device with connection to the Internet, and from anywhere, because it is located on the cloud. The biggest competitors of Microsoft Teams are Slack and Google Meet. Teams is more advanced in creating teams and channels, allowing integration with more than 500 applications, while Slack with only 10 applications on a free plan. Slack, on the other hand, has the advantage of supporting third-party call and video calling services. Google Meet is focused on video meetings, offering integration first for its tools and then for others, unlike Teams, which is focused on conversations. In the circumstances of the global pandemic, the COVID - 19 Teams has greatly contributed to the business world and the smooth running of teaching in the education system. The value of a platform such as Microsoft Teams is recognized in these situations.
