Verify and Restore Your Previous One-Time Office License
If you previously purchased a one-time license like Office 2016 for Mac, you do not need to buy Office 2021 unless you want new features. You can re-activate your older version to remove read-only mode.
Microsoft 365 is a subscription service that restricts document editing once it expires. However, one-time purchases like Office 2016 or Office 2021 do not require annual renewals. You can switch your activation back to your lifetime license.
Navigate to account.microsoft.com in your web browser and sign in with the Microsoft account associated with your previous Office 2016 one-time purchase.
Click on the 'Services & subscriptions' tab located in the top navigation menu of your account dashboard.
Scroll past the expired Microsoft 365 subscription and find your Office 2016 for Mac license in the products list.
Click the 'Install' button next to your Office 2016 license to download the compatible installer for your Mac, then run the installer.
Open any Office application (like Word or Excel) and sign in when prompted to activate the software using your one-time license, resolving the read-only restriction.

Contact Microsoft Support for Refund or Subscription Investigation
If you mistakenly purchased Microsoft 365 or suspect a fraudulent charge, you can request a refund or investigation through official support channels.

Frequently Asked Questions
Does Office 2016 for Mac expire like Microsoft 365?
No, Office 2016 for Mac is a one-time purchase. Unlike Microsoft 365, which requires a monthly or annual subscription, a one-time license never expires, though it does not receive new feature updates.
Why did my Office apps enter read-only mode?
Office apps enter read-only or reduced-functionality mode when an active Microsoft 365 subscription expires. To edit documents again, you must renew the subscription or activate the software with a valid one-time license.
Is it mandatory to upgrade to Office 2021 after my subscription ends?
No, upgrading to Office 2021 is not mandatory. If you already own an older one-time license like Office 2016, you can continue using it, provided it is still compatible with your current macOS version.
Can I get a refund if I bought Microsoft 365 by mistake?
Yes, refunds are possible depending on the purchase date and your region. You must contact Microsoft Support directly through your account dashboard to initiate a refund request for an accidental subscription purchase.
