Microsoft Teams

Deeply integrated into the Microsoft 365 ecosystem, Teams is a powerhouse for organizations already invested in Microsoft's suite. It combines persistent chat, video meetings, file collaboration, and app integration into a single hub. For large teams, it supports meetings of up to 1,000 participants and live events for up to 20,000. Its strength lies in seamless collaboration on Office documents, advanced security/compliance controls via Azure, and direct routing for telephony.

The value is exceptional for Microsoft 365 subscribers, as it bundles comprehensive communication tools with productivity software, making it the top choice for enterprises seeking a unified platform.
