Microsoft Teams, the company's Slack competitor with deep integrations into the Office 365 apps, has seen a lot of pickup over the last few months, with over 125,000 organizations now using it in one form or another.
Microsoft is promising "a new, modern Skype infrastructure delivering enterprise-grade voice, video and meetings experiences".
Microsoft 365 F1 also includes two gigabytes of cloud storage, and other features such as the company's cloud-based Advanced Threat Analysis, Defender Antivirus and Device Guard for Windows 10.
Microsoft said that Teams will be the central tool for what it calls "intelligent communications", and it laid out plans for new features such as surfacing documents ahead of a meeting, recording and transcribing discussions, and subsequently adding notes and recordings to relevant Teams channels for review.
