To transfer a one-time purchase Microsoft Office license to a new computer, you must first uninstall it from the old device, then install and activate it on the new one using your Microsoft account. For Microsoft 365 subscriptions, simply install Office on the new computer and sign in to activate.
Key Takeaways
- License Type is Crucial: Retail one-time purchase licenses (like Office 2021) are transferable, but OEM licenses that come pre-installed on a computer are not.
- Deactivation is Key: You must uninstall Office from your old computer to release the license before you can activate it on a new one.
- Microsoft Account is Your Hub: For modern Office versions, your license is tied to your Microsoft account, which you'll use to download, install, and activate the software.
- Microsoft 365 is Simpler: Subscription licenses are account-based and allow for multiple active installations, making the move to a new device seamless.
- Phone Activation is a Backup: If you encounter an activation error online, the 'Activate by telephone' option is the official method to resolve it with Microsoft's help.
Can You Transfer a Microsoft Office License?
Yes, you can transfer most Microsoft Office licenses you purchased separately, but the specific process depends entirely on the type of license you own. Retail versions of one-time purchase products like Office 2019 and Office 2021 are designed to be moved from one machine to another. In contrast, OEM (Original Equipment Manufacturer) licenses, which are pre-installed by the computer's manufacturer, are tied to the original hardware and cannot be transferred. Microsoft 365 subscriptions offer the most flexibility, as they are linked to your account and allow you to sign in and out of devices at will.
How to Transfer a One-Time Purchase License (Office 2021/2019)
Follow these steps to move your perpetual Office license to a new computer. This process applies to retail versions of products like Office Home & Student, Home & Business, and Professional.

Step 1: Confirm Your License Type
Before you begin, ensure your license is a transferable retail version. If Office came pre-installed on your old computer when you bought it, it is likely an OEM license and cannot be moved. If you purchased Office separately from a retailer, you have a retail license and can proceed.

Step 2: Uninstall Office from the Old Computer
To free up your license for the new machine, you must first remove Office from the old one. On Windows, go to Settings > Apps > Apps & features. Find your Microsoft Office installation in the list, select it, and click Uninstall. Following the uninstallation process deactivates the license on that device, making it available for your new computer.

Step 3: Install Office on Your New Computer
On your new computer, open a web browser and go to the official Microsoft account page: account.microsoft.com/services. Sign in with the same Microsoft account you used when you first activated Office. Find your Office product in the list of purchases and click the Install button to download the setup file. Once downloaded, run the installer and follow the on-screen instructions.
-
Step 4: Activate Office on the New Computer
After the installation is complete, open any Office application like Word or Excel. You will be prompted to activate the software. Sign in with your Microsoft account to complete the activation online. If the system incorrectly states that the license is still in use, you will see an activation wizard. According to Microsoft Support, you may need to choose the Activate by telephone option. Follow the prompts to speak with a support agent who can verify your license and complete the activation.
How to Use Microsoft 365 on a New Computer
Moving a Microsoft 365 subscription to a new computer is much simpler because the license allows for multiple active installations. You just need to install the applications on the new device and sign into your account to activate them.
-
Step 1: Install Office from Your Microsoft Account
On your new PC or Mac, navigate to office.com and sign in with the Microsoft account associated with your subscription. Click the Install Office button and follow the prompts to download and run the installer.
-
Step 2: Sign In to Activate
Once installed, open any Office app. When prompted, sign in with your Microsoft 365 account credentials. The software will verify your active subscription and automatically activate.
-
Step 3: Manage Your Devices (Optional)
Microsoft 365 plans have a limit on the number of devices you can be signed into at once (e.g., five for Microsoft 365 Personal). If you've reached your limit, you can free up an installation slot by visiting your Microsoft account page at account.microsoft.com/services and signing out of an old or unused device remotely.
Common Transfer Problems and Solutions
Even when following the correct steps, you might encounter an issue. Here’s how to troubleshoot the most common problems when transferring your Office license.
What if activation fails with a 'Maximum Activations Reached' error?
This error typically means the Microsoft activation servers have not yet registered that the software was uninstalled from the old computer. The official solution is to use the telephone activation option in the activation wizard. Explain the situation to the support agent, and they can reset the activation count for your license key.
What if my old computer is broken or inaccessible?
If you cannot access your old computer to uninstall Office, proceed directly with installing it on your new machine. When you attempt to activate, it will likely fail. At this point, use the telephone activation method. You will be able to explain to the Microsoft support representative that the old hardware failed, and they can assist in activating the license on your new device.
My license is OEM. What are my options?
If you've confirmed your license is an OEM version, it is non-transferable and your only option is to purchase a new, genuine license for your new computer. This ensures you receive all necessary updates and support. You can purchase a one-time license like Microsoft Office 2021 Home & Business or the latest Microsoft Office 2024 Professional Plus for a lifetime of use without subscriptions.
Frequently Asked Questions
Can I transfer Office to a new computer without the product key?
Yes, for modern versions like Office 2019 and newer, your license is linked to your Microsoft account. You activate the software by signing in with your account, so you do not need to re-enter the product key after the initial setup.
How many times can I transfer my Office license?
According to Microsoft's Software License Terms, a retail license can generally be transferred to a new computer you own once every 90 days. This restriction is waived if the transfer is necessary due to a hardware failure.
What happens if I don't uninstall Office from my old computer?
If you fail to uninstall Office from the original machine, you will almost certainly encounter an activation error on the new computer. The system will detect the license is still active elsewhere, requiring you to use the phone activation method to resolve the conflict.
Can I transfer my Office license to a different person?
No, a retail Office license is for your use only and cannot be transferred to another person. The license is tied to your Microsoft account and is non-transferable to another user's account.
