Completely Uninstall and Reinstall Office for Mac

Removing all trace files of a mismatched license and reinstalling directly from your Microsoft account often resolves subscription recognition issues.

Sometimes, the version of Word installed on your iMac does not match the license you purchased (e.g., installing the Microsoft 365 version when you own a one-time purchase of Office 2021). A clean installation directly from your account page ensures the correct version is applied.

1
Remove Existing Licenses

Download and run the official Microsoft license removal tool for Mac to clear any corrupted or conflicting activation data from your iMac.

2
Uninstall Microsoft Word

Open the Applications folder in Finder, locate Microsoft Word (and other Office apps), and drag them to the Trash.

3
Download the Correct Installer

Sign in to your Microsoft account online, navigate to 'Services & subscriptions', and download the specific Office installer that matches your purchase.

4
Reinstall and Activate

Run the downloaded installer. Once finished, open Microsoft Word and sign in with the correct Microsoft account to activate the software.

Frequently Asked Questions

Why does Word say it cannot find my subscription on my Mac?

This typically occurs if you are signed in with an email address different from the one used to purchase your Microsoft 365 subscription, or if corrupted background license files are preventing the app from verifying your account status.

Can I use Microsoft Word on my iMac without a Microsoft 365 subscription?

Yes, if you purchased a one-time standalone license (such as Office Home & Student 2021). However, you must ensure you download the exact standalone version installer from your Microsoft account, rather than the Microsoft 365 version.

What is the OfficeLicenseHelper on a Mac?

OfficeLicenseHelper is a background process that runs on macOS to verify and manage Microsoft Office subscriptions and licenses. Disabling it temporarily in your Mac's System Settings during a reinstall can sometimes bypass persistent activation loops.
