How to Reinstall and Activate Microsoft Office on a Replacement Mac
Question details
The user needs to reinstall and activate a one-time purchase Microsoft Office Home license on a replacement MacBook Air after returning the original Mac.
- Product
- Microsoft Office Home for Mac
- Device & OS
- Mac (MacBook Air)
- Scenario
- Transferring a one-time retail Microsoft Office license to a new replacement Mac after the original device was returned without uninstalling the software.
- Observed behavior
- Activation on the new Mac fails or is prevented because the one-time license remains associated with the hardware of the returned Mac.
Ensure you have access to the Microsoft account used to purchase or redeem the original Office license, and locate your 25-character product key card if you bought a physical copy.
Contact Microsoft Support to Transfer the License
Use this solution if your original Mac was returned or is broken, preventing you from manually uninstalling the software to release the hardware-bound license.
A one-time Microsoft Office Home license is permanently tied to the hardware it is first activated on. If you return or sell the Mac without completely uninstalling Office, the Microsoft activation server still registers the license as 'in use'.
Since the original MacBook Air is no longer accessible, you cannot manually unlink it. You will need to contact Microsoft Support to verify your purchase and have them manually release the license so it can be activated on the replacement Mac.
Open a web browser on your replacement Mac and navigate to the official Microsoft Support contact page (support.microsoft.com/contactus).
Click on 'Microsoft 365' or 'Office', type 'Activate Office on new Mac' into the search box, and select 'Get Help'.
Scroll to the bottom of the page and click 'Contact Support'. Choose 'Microsoft 365 and Office' as the product, and select 'Activate my product' as the category. You will then be given options to chat with a support agent in your browser or request a phone callback.
Explain to the agent that the original Mac was returned. Provide your Microsoft account details and product key if asked. Once the agent releases the license, open any Office app on your new Mac, sign in, and follow the prompts to complete the activation.

Frequently Asked Questions
Can I use my one-time Office Home license on two Macs at the same time?
No. A one-time retail license for Microsoft Office Home & Student or Home & Business can only be installed and activated on a single computer at any given time.
What happens if my original Mac is broken and I can't uninstall Office?
If you cannot access the original Mac to uninstall the software, the Microsoft server still registers the license as active on that machine. You must contact Microsoft Support directly via chat or phone to have them manually deactivate the old installation.
How do I completely remove Office from my old Mac before returning it?
To completely uninstall Office, open Finder, go to the Applications folder, and drag all Microsoft Office apps (Word, Excel, PowerPoint, etc.) to the Trash. You should also remove associated Microsoft files from your user Library folder to ensure a clean uninstallation.
