Tom Arbuthnot, Co-Founder of Empowering.Cloud, and Rolf Tröndle, Founder of ChangeCockpit, both Microsoft MVPs, pick out the 11 Microsoft 365 changes with the biggest enterprise impact this month.

The headlines: Microsoft Teams Phone Agent is now generally available (MC1482800), GPT-6.1 Sol and Claude Sonnet 5.5 are arriving in Copilot with new usage caps (MC1483844), Conditional Access now covers Outlook attachments (MC1472591) and Security Copilot is included in E5 and E7 (MC1478465).

This post summarises the highlights. Watch the full episode on YouTube for the details and demos.

Summary

• Act now: review your Conditional Access policies before users lose access to attachments in Outlook on the web and the new Outlook. If you want GPT-6.1 Sol in Copilot, enable OpenAI as a subprocessor.
• Prepare users: SharePoint hero link sharing is rolling out now, and the new SharePoint mobile experience lands by mid-October.
• Plan budgets: Teams Phone Agent, the new Copilot models and Security Copilot all lean on usage-based billing. Decide who owns that spend before usage grows.

Tom Arbuthnot (Empowering.Cloud) and Rolf Tröndle (Change Cockpit) pick out the Microsoft 365 enterprise changes worth acting on this month. They cover a new in-country data residency switch (MC1470876, MC1470878) with a 14 December deadline, the EWS switch-off from 1 October (MC1469960), Copilot credit spending controls (MC1470425) and passkeys as a first MFA method (MC1450133).

Tom and Rolf (Change Cockpit) review the enterprise Microsoft 365 changes worth acting on now, including the rumoured Copilot "super app" merging Copilot Chat, Cowork, Autopilot and GitHub Copilot, passkey nudges from 1 September ahead of SMS and voice MFA decommissioning, and Copilot credit spending limits that have stopped working. They also cover Teams Rooms passwordless resource accounts and the removal of the memberOf dynamic membership operator.
