This week, I want to highlight a small but mighty feature in Microsoft Teams that’s now available worldwide. If you work with external users, you’ll know the pain of sharing files. Until now, you had to upload them to OneDrive or—worse—resort to unauthorized platforms. That’s no longer the case. You can now attach files directly in chats with external users, saving time and avoiding frustration. It’s not a brand-new announcement, but its global rollout makes it worth sharing.
On the broader Microsoft 365 front, the standout update for me is the arrival of Claude in Copilot. It’s exciting to see model choice becoming a reality—currently available in Copilot Studio and the Researcher agent.
And for all the SharePoint developers out there: Microsoft just updated their plans—SPFx Field Customizers are here to stay (at least for now). The earlier idea to retire them in favor of JSON column formatting has been shelved. Column Formatting is still great for simpler scenarios, but if you need advanced logic like API calls, SPFx is still your friend.
