Many businesses start using Microsoft Teams because it comes bundled with Microsoft 365 — but soon discover it isn’t always the best fit:

❌ Too complex and bloated for simple team chat

❌ Steep learning curve for non-technical users

❌ Slow performance on older devices

❌ Poor user adoption outside of the IT department

But what if you could replace Microsoft Teams with a lighter, faster chat app — and still integrate with your Microsoft tools like Outlook, OneDrive, and Office?

Good news: In 2025, there are several great Teams alternatives that work well alongside Microsoft 365. In this guide, we’ll show you the best options — starting with the one we believe works best for modern teams.

What to Look for in a Teams Alternative That Integrates with Microsoft

✅ Chat-first (not overloaded with unnecessary features)

✅ Integrates with Microsoft tools (Outlook, Office, OneDrive, SharePoint)

✅ Faster, simpler UI than Teams

✅ Built-in task/project management

✅ Good admin controls

✅ Cross-platform: desktop + mobile
