Both retail and digital versions offer identical features; the main difference is the delivery method. Reinstallation relies entirely on your Microsoft account.

A retail package includes a physical box with a printed product key, while a digital download ties the license directly to your email or Microsoft account upon online purchase. The applications (Word, Excel, PowerPoint) and features are exactly the same.

1
Link your product key (Retail only)

If you purchased a retail box, navigate to setup.office.com, sign in with your Microsoft account, and enter your 25-character product key to bind the license to your account.

2
Access your Microsoft account on the new Mac

Open a web browser on your new Mac and navigate to account.microsoft.com/services. Sign in with the account linked to your Office 2021 license.

3
Download and install

Locate 'Office Home and Student 2021' in your list of purchased products and click the 'Install' button to download the installer package for macOS.
