Hello,

I can help you figure out what could be wrong, but I need some more information first.

What is your macOS version?

Is your office product purchased from Microsoft or from Apple?

Is it a Microsoft 365 personal or family subscription?

Hi, Barbara Morse

This is not caused by the subscription expiring. macOS 11.7.10 is macOS Big Sur, not iOS, and it is below the minimum required version.

Starting July 13, 2026, Office on older macOS versions can enter reduced-functionality mode. This allows documents to open, but editing, copying, saving, and creating files may stop. The required minimum is macOS 12 Monterey with Office version 16.83 or later.

Please check Apple menu > System Preferences > Software Update. If Monterey or a newer macOS version is available, install it first. Then open Word and select Help > Check for Updates > Update All.

If this Mac cannot be upgraded beyond Big Sur, the required Office update cannot be installed. Reinstalling Word or starting another subscription will not resolve that limitation. The available options are to use Microsoft 365 for the web in a browser, install Office on another supported device, or upgrade the Mac. Your documents remain safe, and the existing subscription is still valid.

Hi, Nicole Wilkerson

Sorry you’re having trouble with Word. This is usually caused by an outdated Office build, saved activation information, or Word being signed in with an account that does not own the subscription.

First, check the macOS version under Apple menu > About This Mac. If the Mac runs macOS 12 or later, open Word and select Help > Check for Updates, then install all available updates. Current activation requires Office version 16.83 or later. Older macOS versions may leave Office in limited-functionality mode, even when the subscription is paid.

Next, visit Microsoft Services & subscriptions and confirm that Microsoft 365 is active. Then quit all Office apps, reopen Word, sign out of every account, and sign in with the exact email address shown on that subscription.

If activation still fails, use the official Office license removal tool for Mac, restart the Mac, and activate Word again. This clears damaged or outdated license information without deleting documents.

If possible, please share the macOS version and the exact activation error code.

Thank you for your patience in reading, I hope this information has been helpful to you.

Good morning! Yes, I agree with the comment that said after a number of years, Microsoft makes the program "Read-Only". I think that's what's happened with my Microsoft Office 2019. It's a complete scam, in my opinion, but it is what it is. I purchased Office 2024 for my Mac and everything's working fine. Thank you!
