Hands-On Microsoft 365 Pulse – Weekly Updates (Week 38)

By João Ferreira Sep 22, 2025 Pulse 0 Comments

This past week, SharePoint introduced the Knowledge Agent in preview, bringing powerful AI capabilities across the platform. Even better, Microsoft made it available on the same day it was announced—no waiting required.

Microsoft Teams features keep coming out like hot cakes, making it challenging to stay on top of everything. With so many announcements coming out, I figured I’d put together a recap of everything that’s been announced since the beginning of summer so you don’t miss the important stuff.

While AI has been stealing the spotlight, another significant change quietly happened this September: the return of the new SharePoint page templates. After briefly disappearing, they’re back—and this time, Microsoft says they’re here to stay.

Each week, I spotlight the most impactful updates across Microsoft 365—whether it’s a major feature release, a hidden gem from the roadmap, or a deep dive into how you can make the most of these tools. From Microsoft Teams enhancements that boost collaboration to SharePoint improvements for better content management and Copilot innovations that bring AI into your workflow, these highlights are designed to help you stay ahead and work smarter. Whenever possible, I’ll also share links to my latest blog posts for practical tips and hands-on guidance.
