From Navy Email to M365 E7: A 30-Year Microsoft Journey (Episode 51)

Most businesses have Microsoft 365. Far fewer know what their license actually includes. Corsica's Microsoft practice lead John Joyner, a 20-year Microsoft MVP and retired U.S. Navy Lieutenant Commander, joins Garrett Wiesenberg to break down the E3, E5, and E7 suites, Business Premium for smaller companies, and what each tier means for security, management, and AI.

John opens with how he got started: bringing email and internet access to 3,500 sailors on the USS Carl Vinson in the mid-1990s, and the 80% drop in emergency Red Cross messages that followed. From there they get practical: why Microsoft 365 is not Office 365, how Defender for Office, Endpoint, Identity, and XDR work as one system, what companies under 300 users get (and miss) with Business Premium, and how the Defender Suite add-on closes the gap. They finish with E7: Copilot, Agent 365, and why governing AI agents matters even if you haven't deployed any.
