Microsoft 365 Fall Changes: What’s Coming, What’s Going (and What to Do)
As the fall season arrives, Microsoft 365 is rolling out several significant updates that every business and IT team should be aware of. From security upgrades in Teams to new features on Copilot iOS, these updates are designed to improve productivity and protect users. Let’s take a closer look at what’s new, what’s being phased out, and what steps you should take to stay prepared.
What’s New in Microsoft 365 This Fall
Microsoft is releasing a fresh wave of improvements across its cloud tools. These changes are designed to help users work smarter and more securely. One of the most exciting updates is happening on mobile. Copilot iOS now allows users to preview Word, Excel, and PowerPoint files directly from the app. This makes it easier to view content, comments, and key information before opening the full document. It is a small change that makes a big difference for people working on the go.
Copilot iOS Makes Mobile Work More Efficient
If you use Microsoft 365 on an iPhone or iPad, the new Copilot iOS update brings better productivity. Users can now preview files inside the app and even ask Copilot questions about a document before opening it. This provides you with quick access to the information you need, eliminating the need to switch between apps or files.
For mobile teams and professionals who need fast answers, this feature helps save time and reduce confusion. It also enhances collaboration by making it easier to stay updated, regardless of your location.
Teams Security Gets a Stronger Defense
Microsoft Teams is also getting smarter and safer. As of this fall, Teams will begin blocking certain types of risky files, such as executable programs that may contain malware. In addition, Teams now warns users if they click on links that could lead to phishing websites. These upgrades are part of a broader focus on enhancing Teams security. They are designed to prevent accidental downloads, protect sensitive data, and stop scams before they reach your users.
How These Teams Security Updates Help Your Business
These changes are especially important for small businesses and teams that rely on Teams for daily meetings and messaging. With stronger protection in place, there is a lower risk of someone clicking on the wrong link or downloading something malicious.
Admins can review and adjust settings in Microsoft 365 to make sure these new protections are active. It is a good idea to notify your team and remind them about safe online habits as well.
What’s Going Away in Microsoft 365
As new features arrive, some older tools and platforms are being phased out.
First, the legacy calendar toggle inside Microsoft Teams is being removed. Everyone will now use the integrated Microsoft 365 calendar view by default. This view includes valuable features such as Copilot and enhanced meeting planning tools.
Next, Microsoft To Do will stop supporting older versions of iOS and macOS. Devices running iOS 16 or earlier, or macOS 12 or earlier, will no longer receive updates for the app. Users will need to update their systems to keep using To Do securely.
Finally, Microsoft 365 apps on Windows 10 are nearing the end of support. While the apps will still function after October 14, 2025, they will no longer receive updates, performance fixes, or improvements. Microsoft recommends upgrading to Windows 11 for the best experience.
What You Should Do Now
To get ready for these changes, here are a few action steps for your business or IT team:
1. Update user devices
Make sure devices are running supported versions of iOS, macOS, and Windows.
2. Communicate calendar changes
Let your team know about the new default calendar in Teams.
3. Enable Teams security features
Check your admin settings to ensure that file blocking and link scanning are enabled.
4. Explore Copilot iOS
Demonstrate to users how to utilize the new file preview features for enhanced mobile productivity.
5. Plan your Windows 11 upgrade
If your team is still using Windows 10, begin the transition early to avoid last-minute issues.
Microsoft 365 is evolving this fall, with a focus on introducing more innovative features and enhancing security. Whether you are exploring new mobile tools like Copilot iOS or protecting your team with better Teams security, now is the time to prepare. Staying ahead of these changes will help your business run smoothly and stay secure through the rest of the year.
