What is Microsoft Teams?
Microsoft Teams is a collaboration and communication platform that brings chat, video meetings, calling, and file collaboration together, deeply integrated with the Microsoft 365 ecosystem. For the enormous number of organisations that already run on Microsoft's productivity tools, Teams is the natural hub where work and communication come together — chat with colleagues, meet over video, co-author documents, and access the apps and files you use every day, all in one place. Its tight integration with Office applications is the defining advantage that makes it the default choice for so many businesses.
Teams organises communication around persistent chat and structured team spaces with channels, so conversations stay connected to the projects and groups they belong to. Its video meetings are robust and feature-rich, supporting everything from quick calls to large webinars, with screen sharing, recording, and collaboration tools built in. Because it lives inside Microsoft 365, documents in Word, Excel, and PowerPoint can be co-edited directly within Teams, files are managed through the same trusted storage, and identity and security are handled by the organisation's existing Microsoft administration. It also supports phone calling, an app ecosystem for extending functionality, and the enterprise-grade compliance and governance large organisations require.
Microsoft Teams is used across businesses of every size, but it's especially compelling for organisations already invested in Microsoft 365, where it adds powerful communication on top of tools they already pay for and trust. The value is consolidation and integration: rather than bolting a separate chat or meeting tool onto their stack, these organisations get a unified platform where communication, meetings, and document collaboration are woven together and centrally managed. For IT departments, the single ecosystem simplifies administration and security; for employees, it means less switching between apps. As the communication backbone for a vast number of companies, Teams has become a central part of how modern organisations coordinate, meet, and get work done together.
What is Slack?
Slack organizes team communication into channels, with huddles, threads and a deep app ecosystem.
