Fix Office for Mac Saying It Is Not Activated After Activation
Question details
Microsoft Office for Mac repeatedly prompts for activation and prevents saving files despite showing as already activated.
- Product
- Microsoft Office for Mac (Word, Excel)
- Device & OS
- Mac
- Scenario
- After performing a macOS update and a system file transfer or migration.
- Observed behavior
- Word and Excel continuously request activation, completely blocking the ability to save files, even when the software interface reports that Office is already activated.
Ensure you know the exact Microsoft account credentials tied to your Office subscription or purchase, and save any open work to an external drive or cloud storage if possible.
Clear Local Office Activation Credentials
Use the official Microsoft License Removal Tool to delete corrupted or outdated license files on your Mac, which is the most common fix for persistent activation loops.
When you transfer files to a new Mac or perform a major update, the hidden activation tokens can become mismatched with your hardware. Clearing these credentials forces Office to generate a fresh, valid activation token.
Navigate to the official Microsoft support website and download the Mac License Removal Tool (.pkg file).
Ensure Word, Excel, PowerPoint, and Outlook are completely closed. Force quit them if necessary.
Open the downloaded .pkg file and follow the on-screen installation prompts to run the script. This will wipe the local Office activation state.
Restart your Mac, launch Microsoft Word, and sign in again with your Microsoft account to re-activate the software.
Verify Your Account License and Office Version Match
Ensure the version of Office installed on your Mac correctly corresponds to your specific Microsoft 365 subscription or one-time purchase license.

Frequently Asked Questions
Why does my Mac say Office is not activated after a file transfer?
Transferring files via macOS Migration Assistant or Time Machine can copy outdated or corrupted license files. The Office application detects a mismatch between your Mac's new hardware signature and the old transferred license, triggering repeated activation prompts.
Will the Microsoft License Removal Tool delete my Word and Excel files?
No, the license removal tool is completely safe for your data. It only clears the hidden activation credentials and product key files on your Mac. Your personal documents, spreadsheets, and settings remain untouched.
What if I have a one-time purchase like Office 2019 or 2021?
If you own a one-time license, you must ensure that the specific software package for that year is installed. If a system update or file transfer upgraded your apps to the generic Microsoft 365 suite, it will reject your one-time license during activation. You will need to download the legacy installer from your Microsoft account.
