The Top 10 Essential Microsoft 365 Copilot Use Cases

Let’s be honest. When Microsoft 365 Copilot landed in early 2024, most of us didn’t know what to expect. Would it be another fleeting “revolution,” or would it genuinely help us manage the daily flood of meetings, emails, and documents?

At Planet Technologies, we dove in headfirst. Working with a wide range of organizations, from large enterprises to small businesses, we observed firsthand what really works, what falls short, and what makes people say, “Ah ha!”

Here is what we discovered: the challenges Copilot truly addresses, the scenarios users love most, and why these use cases deliver real, everyday value.

The Challenge: Information Overload

Most knowledge workers are buried beneath waves of emails, meetings, and files. Hours are lost searching for documents, summarizing endless email chains, and constantly taking notes. This inefficiency is exactly what Copilot was designed to resolve.
