Microsoft 365’s August 2026 updates span Teams, Outlook, SharePoint, OneDrive, Entra, Intune, Copilot, and admin tools to boost productivity, security, and governance.

Intune adds unattended remote support for IT troubleshooting, with registry inventory for remote diagnostics and a shift from app-targeting to assignment filters for policy application by January 2027.

Entra shifts to passkeys as the default authentication method, phasing out SMS-based MFA to strengthen security and cross‑platform compatibility.

Teams imposes mandatory participation consent for AI usage policies before meetings, moves live captions to a right-hand panel, improves real‑time security monitoring, and provides a single‑pane troubleshooting view, with Live Chat and Google Calendar sync retiring by October 2026.

Overall, Microsoft aims to strengthen security, streamline collaboration, and expand AI‑driven productivity across the suite, including several retirements and policy shifts through 2027.

Administrative updates include Defender enhancements for threat detection, multi‑tenant agent management in public preview, Purview adaptive scopes for lifecycle statuses, and a 50% discount on Purview E5 compliance add-ons for Business Premium users through December 2026.

Copilot enhancements broaden AI productivity with email drafting, interactive PowerPoint tools, unified apps, third‑party integrations, a simplified UI, and features like “Ask Copilot” in Teams and session sharing.

Outlook introduces event-based email filtering, mobile drag‑and‑drop calendar rescheduling, expands business mailbox storage to 100GB by September 2026, and retires legacy calendar sharing in favor of cross‑tenant access policies between late 2026 and early 2027.

SharePoint and OneDrive updates focus on stronger file sharing with a new third‑generation sharing experience, faster macOS sync, and expanded permissions reporting to improve collaboration and security.
