- Product

- Device & OS
- Mac
- Scenario
- Activating a one-time purchase Office license on a Mac computer to start editing and saving files.
- Observed behavior
- Office displays a message requesting a Microsoft 365 trial or subscription, locking the user out of document editing and saving capabilities despite having a lifetime license.
Ensure you have the login credentials for the exact Microsoft account that was originally used to purchase or link your Office Home & Business 2021 license.
Verify Account and Use License Removal Tool
Check that your license is tied to your account and clear out any old or conflicting license files on your Mac that might be triggering the Microsoft 365 prompt.
Often, Macs retain old trial or subscription license files from previous installations of Microsoft 365. This causes the software to ignore your valid Office 2021 one-time purchase. Clearing these old files forces the software to recognize the correct license.
Open a web browser, go to account.microsoft.com/services, and sign in with your Microsoft account to confirm your Office Home & Business 2021 license is listed.
If the license is present but Office still prompts for a subscription, download Microsoft's official Office license removal tool for Mac from the Microsoft support website.
Open the downloaded tool and follow the on-screen prompts to completely clear previous activation files from your Mac.
Restart your Mac, open Word or Excel, and sign in again using the Microsoft account associated with your Office 2021 purchase to activate the software.
Switch to WPS Office for a Hassle-Free Mac Experience

- 1. Download WPS Office: Visit the official WPS website and download the Mac version for free.
- 2. Install the Application: Open the downloaded package and drag the WPS Office icon to your Applications folder.

Frequently Asked Questions
Why is my Office 2021 Mac asking for a Microsoft 365 subscription?
This usually happens if you are signed into the wrong Microsoft account, or if leftover license files from a previous Microsoft 365 installation or trial are still on your Mac. Using the license removal tool clears this conflict.
Do I have to pay monthly for Office Home & Business 2021?
No. Office Home & Business 2021 is a one-time purchase. You do not need a Microsoft 365 subscription to edit and save your files.
Will I lose my files if I use the Microsoft Office license removal tool?
No. The license removal tool only deletes hidden activation and licensing files on your Mac. Your actual documents, spreadsheets, and presentations will remain completely unaffected.
