Users need to resolve an issue where Microsoft Office for Mac opens documents in read-only mode, preventing them from editing or saving files.

Fix Microsoft 365 and Office for Mac Opening in Read-Only Mode

Product: Microsoft 365 / Office for Mac
Device & OS: macOS
Scenario: Opening and attempting to edit documents in Office Home and Business 2016 or Microsoft 365 after a macOS or Microsoft software update.
Observed behavior: Office applications launch in read-only mode, disabling editing capabilities and prompting the user about subscription or account issues.

Before you start

Ensure you have your Microsoft account credentials ready and confirm your current macOS version by checking 'About This Mac' from the Apple menu.

Solution 1Recommended

Verify Your Microsoft Account and Subscription

Check if your Office 2016 purchase or Microsoft 365 subscription is properly linked to your active Microsoft account.

Read-only mode often triggers when the Office application cannot verify your license. This frequently happens if you are signed out, using the wrong account, or if your subscription has expired.

Sign in to Microsoft Services

Open a web browser and navigate to the Microsoft account Services and subscriptions page.

Check Account Association

Verify Active License

Look under your active subscriptions to ensure your license is valid. If it is associated with a different account, switch accounts in your Mac Office application.

Verify Your Microsoft Account and Subscription

Use Office.com as a Backup: If your desktop license has expired, you can still use Office.com for limited browser-based editing for free.

Solution 2

Check macOS Compatibility for Office 2016

Ensure your version of Office is still supported by your current macOS release.

Can I still edit my files if Office 2016 is unsupported on my Mac?

Yes. You can use the limited browser-based editing features on Office.com by signing in with your Microsoft account, or you can switch to a free desktop alternative like WPS Office to edit your files natively.

How do I activate my Microsoft 365 subscription on a Mac?
