Microsoft Teams: Best Overall Free Unified Communications Platform

Overall Score: 4.57 / 5

What We Liked

Where It Falls Behind

Microsoft Teams Monthly Pricing (per User)*

*All paid plans require an annual prepayment.

Microsoft Teams is our best free unified communications as a service platform due to its excellent range of features for collaboration and productivity. It offers everything in its generous free plan—unlimited group meetings, unlimited group chat, file sharing, and cloud storage. It also includes real-time collaboration within Microsoft 365 apps, including Word, Excel, and PowerPoint—perfect for companies consistently using Microsoft products.

Teams is a popular collaboration choice for businesses needing a team messaging app with built-in video conferencing. This reduces the need for app switching because you can chat, meet, share files, and assign tasks on a single screen. Upgrading to premium plans unlocks desktop versions of Microsoft 365 apps, app integrations, expanded cloud storage, and standard security features.

One major downside of Teams is that many users find it frustrating to navigate. While it looks highly organized, the compartmentalized structure of its sidebar increases the user’s learning curve. If you simply need a team chat app without the extra features, consider Slack. This provider is particularly known for its user-friendly interface, ideal for users across skill levels.
