Microsoft 365 Evergreen: Key Updates & What's New – October 2026

Microsoft releases updates across Teams, SharePoint, OneDrive, Outlook, security and compliance every month. Some are game-changing, and others roll out quietly but still affect how your organisation works and stays secure. This is Core's monthly Microsoft 365 update webinar for October 2026.

It covers recently released features, changes that may need action from IT or security teams, retirements, roadmap shifts and configuration updates, and what to prepare for next. It's drawn from Core's Evergreen service, which tracks Microsoft's change cycle for its customers, so it's a curated list rather than a generic roadmap recap.

It comes from a managed services provider promoting its own Evergreen service, but the update summary is useful whoever looks after your Microsoft 365 tenant. It was presented live on 13 October 2026.
