Just saw this today and wanted to pass it on. Ignite is free to register and there are tons of sessions and learning tracks. It has helped me in the past get a better handle on the cutting edge of our 365 subscriptions and especially what security tools come with Exchange Online and Advanced Threat Protection.
The event is at Chicago’s McCormick Place - Lakeside Center on April 15-16, 2020.
