What is the name of Microsoft's video conferencing app?

Microsoft's video conferencing app is Microsoft Teams.

Microsoft Teams is a collaboration platform that combines video meetings, chat, voice calls, file sharing, and team workspaces. Microsoft introduced Teams in 2017 as part of its broader productivity software lineup, and it became especially prominent as organizations shifted to remote and hybrid work. Meetings can be joined through desktop and mobile apps or a web browser.

Teams is closely integrated with Microsoft 365. Users can collaborate on files stored through services such as SharePoint and OneDrive, schedule meetings with Outlook, and work inside channels organized around projects or departments. This makes Teams more than a standalone video-call program.

Skype is the most common historical mix-up: Microsoft also owns Skype, but Skype and Teams are separate products. Slack is primarily known for workplace messaging and collaboration, while Zoom is a separate company's video-meeting platform. Teams can support both scheduled meetings and quick calls inside an ongoing team conversation.
