Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
On a Mac, this usually happens when Office is installed from the Mac App Store or the Office 2024 license is not activated correctly. The Mac App Store version requires a Microsoft 365 subscription and does not use a one-time Office Home 2024 license.
Try this in order:
- In any Office app, make sure it is signed in with the same Microsoft account that was used to purchase Office Home 2024.
- If Excel was installed from the Mac App Store, remove the Office apps:
- Close Word, Excel, PowerPoint, and Outlook.
- Open Finder > Applications.
- Control-click Word, Excel, PowerPoint, and Outlook, then choose Move to Trash.
- Reinstall Office directly from Microsoft, not from the Mac App Store. If needed, use the Mac installer package for Office:
- After installation finishes, open Excel and activate it with the Microsoft account that owns the Office 2024 purchase.
- If Excel still shows read-only or asks for Microsoft 365, sign out of Excel, restart the Mac, then open Excel and sign in again.
If Office apps can open and print files but cannot edit, save, or create new files, that is reduced functionality mode and points to an activation issue.
