One mail on Friday: what changed in Microsoft 365 security this week, whether it affects you and what to check.

What is in an issue

• What changed: the week's Microsoft 365, Entra, Defender, Purview, Intune, Windows and Copilot changes that need someone to act, each with its date and its source.
• Am I affected: who has to act, and a read-only check where we have one.
• What to do: the first step, and a link to the full brief with impact and rollback.
• Dates coming up: deadlines in the coming weeks from the deadlines guide.
• Nothing else. No sales mails, no sponsored items, and no open or click tracking.

Urgent alerts

Tick "Urgent alerts" if you also want a short mail on the day a Microsoft 365 change needs action now, for example an exploited vulnerability with a fix to deploy. Most weeks there is none.
