Hi,
There was an update to Microsoft 365 and Office on macOS starting July 13, 2026: https://support.microsoft.com/en-us/office/lifecycle/officeinstall/update-m365-office-macos-ios
What is the current version of macOS you are using? Make sure your Mac is updated and running macOS 12 or later.
To check for updates, go to Apple menu > System Settings > General > Software Update, then click Update Now. Apply all available updates.
Then, also check if your Office apps are updated to the latest version.
Close all Office applications and open Microsoft AutoUpdate by going to Finder > Applications > Microsoft AutoUpdate. Select Update All, or update Word individually if an update is available. Once the updates are complete, open Word again and try activating it.
If you installed Word from the Mac App Store, open the App Store, select Updates, and update Microsoft Word or select Update All.
If your Mac cannot be updated to the required macOS version, you can use Microsoft 365 on the web or use Office on a different supported device.
