How Does the Office Insider Program Work?

If you’re asking “how does the Office Insider Program actually work?”—it’s all about test-driving Microsoft 365 updates before the world sees them.

The Microsoft 365 Insider Program, often searched under “what is Office Insider Program,” operates through two distinct update channels:
