How To Transfer Microsoft Office To Another Computer
Whether you’ve purchased a new device for work or upgraded your home PC, one of the first tasks you’ll need to complete is transferring your Microsoft Office applications. Many people wonder if they can simply copy program files — unfortunately, it’s not that straightforward. To ensure a smooth setup, you’ll need to deactivate the license on your old computer, reinstall Office on the new one, and reactivate it with your Microsoft account or product key.
In this guide, we’ll walk you step by step through how to transfer Microsoft Office to another computer, along with professional tips on handling licensing, backups, and ensuring none of your files or settings are lost in the process.
We’ll also discuss when businesses should consider professional Microsoft 365 migration services for larger or more complex transfers.

Step 1: Check Your License Type
Not all Office licenses allow transfers.
-
Retail license: Can be moved to another computer, as long as it’s only active on one device at a time.
-
OEM license: Pre-installed on your device by the manufacturer and cannot be transferred.
-
Volume license: Typically used by organizations; transfers depend on your company’s agreement.
Tip: You can check your license type by logging into your Microsoft account or checking the “Product Information” section in any Office app.
Step 2: Deactivate Office on the Old Computer
Before installing on a new device, you’ll need to sign out or deactivate Office on the old one.
-
Go to Microsoft Office Account.
-
Sign in with the account linked to your Office license.
-
Locate your current installation and select Deactivate Install.
This step frees up the license for use on another computer.
Step 3: Install Office on the New Computer
Now that your license is available, you can install Office on your new PC or laptop:
-
Visit Office.com/setup or log into your Microsoft account.
-
Download the Office installer package.
-
Run the setup file and follow the on-screen instructions.
-
Once installed, launch any Office app and sign in with your Microsoft account.
Your subscription or license will activate automatically.
Step 4: Transfer Your Files and Settings
While Office apps themselves transfer through reinstallation, your documents, templates, and email settings (if using Outlook) need to be moved manually:
-
Documents: Copy files from the
Documentsfolder to a USB drive, cloud storage (OneDrive), or external hard drive. -
Outlook settings: Export your Outlook data file (.PST) from the old computer and import it on the new one.
-
Templates and Add-ins: Manually move any custom templates or add-ins you’ve created.

-
Minimizing downtime during the migration process.

2. What if my Office license is OEM?
OEM licenses are tied to the original hardware and cannot be transferred. You will need to purchase a new license.
