Solution 1Recommended

Remove Old License Files and Reinstall Office 2021

Clear out the conflicting Office 2019 volume license data using Microsoft's official removal tool, then perform a clean installation of Office 2021 to ensure proper activation.

macOS often retains old software license files even after you upgrade. This means the system prioritizes your previous Office 2019 Volume License over your new 2021 purchase. Removing these hidden files is necessary to allow the new activation to register.

1
Download the License Removal Tool

Visit the official Microsoft Support website, search for 'How to remove Office license files on a Mac', and download the official License Removal Tool (.pkg file).

2
Run the Tool to Clear Licenses

Open the downloaded .pkg file and follow the on-screen installation prompts. This will securely erase all previous Office license files from your Mac's system Library.

3
Uninstall Existing Office Apps

Navigate to the 'Applications' folder in Finder. Select all existing Microsoft Office apps (Word, Excel, PowerPoint, Outlook) and drag them into the Trash.

4
Reinstall Office Home & Student 2021

Log into your Microsoft account dashboard online, navigate to your 'Services & subscriptions' page, and download the Office Home & Student 2021 installer for Mac. Run the installer to completion.

5
Activate the New Version

Launch any newly installed Office application, such as Microsoft Word. When prompted, sign in with the Microsoft account associated with your Office 2021 purchase to activate the software.

Data Safety: Running the license removal tool only deletes the background activation files. It will not delete or modify your personal documents, spreadsheets, or Outlook emails.

Frequently Asked Questions

Why does my Mac still show Office 2019 after installing Office 2021?

Macs often cache older volume licenses within the system Library. If the previous Office 2019 license files are not manually removed, the system will prioritize them over the newly installed Office 2021 license.

Will removing the Office license delete my saved documents?

No. The Microsoft License Removal Tool only targets the hidden system files responsible for software activation. Your personal documents, spreadsheets, and emails remain entirely safe.

Do I need to uninstall Office 2019 before installing Office 2021 on Mac?

Yes, it is highly recommended to move all older Office applications to the Trash and clear the old license files to prevent software and activation conflicts before installing the new version.
