Install and Activate via Your Microsoft Account
Since Apple purchases do not provide a product key, your subscription is digitally linked to your Microsoft account. You can use this account to download and activate Office on your PC.
When you purchase Microsoft 365 through the Apple App Store, the license is bound to the Microsoft account you sign in with during the initial setup. You do not need a product key to use the software on other devices.
Open a web browser on your Windows PC and navigate to www.office.com. Click 'Sign in' and enter the Microsoft account credentials associated with your Apple purchase.
Once logged into your account dashboard, locate and click the 'Install apps' or 'Install Microsoft 365' button in the upper right corner to download the setup file.

Open any installed application, such as Word or Excel. When prompted to activate, choose to sign in, and enter the same Microsoft account to verify your subscription.

Frequently Asked Questions
Can I use an Apple-billed Microsoft 365 subscription on multiple devices?
Yes. A Microsoft 365 Personal or Family subscription allows you to install and sign in to Office apps on multiple devices simultaneously, including Windows PCs, Macs, tablets, and phones, regardless of whether you purchased it through Apple or Microsoft.
Why am I asked for a product key when I bought Microsoft 365 through Apple?
Apple handles the billing for subscriptions purchased via their App Store and does not issue traditional 25-character product keys. If prompted for a key on your PC, ignore it and simply choose the option to sign in with the Microsoft account linked to your purchase instead.
How do I cancel or manage a Microsoft 365 subscription bought on an iPad or Mac?
Since your subscription was purchased through Apple, you must manage or cancel it via your Apple ID settings on an iOS device or through the App Store on a Mac. You cannot manage the billing details for an Apple-purchased subscription directly through your Microsoft account dashboard.
