Microsoft Teams

Microsoft Teams is a communication platform created by Microsoft, which is part of the Microsoft 365 suite of products. It serves as a business-oriented alternative to services like Slack, offering features such as chat, videoconferencing, file storage, and application integration. Microsoft Teams has replaced other collaboration platforms like Skype for Business and Microsoft Classroom.

During the COVID-19 pandemic, the demand for Teams, as well as similar software like Zoom and Google Meet, increased significantly as virtual meetings became the norm. As of January 2023, Microsoft Teams had around 280 million monthly users. However, newer versions of Teams restrict the use of web browsers from other vendors to open links.
