Activate Microsoft 365or a non-subscription version of Office
When you start an Microsoft 365 app that's not activated, you'll be prompted to sign in to Microsoft 365. Be sure to sign in using the Microsoftaccount, or work or school account, that you used to buy or subscribe to Microsoft 365.
Note:If Microsoft 365 came pre-installed on your new device, see Activate Office that's pre-installed on a new Windows device.
If the Activation wizard appears, Microsoft 365 needs your help to activate. Follow the prompts in the wizard to activate Microsoft 365.

You'll see this screen if you sign in to Microsoft 365 that was pre-installed on a new device but don't have an Microsoft 365 product associated with your account.
To use Microsoft 365 on your new device, you can activate Microsoft 365 as a 1-month trial of Microsoft 365 Family. You can also buy Microsoft 365, add Microsoft 365 to an existing Microsoft 365 subscription, or enter a product key from a new product key card. If you have an older copy of Microsoft 365, you can install that instead.

A digital product key is transmitted to your PC, so you won't need or receive a printed product key. You activate Microsoft 365 by signing in with a Microsoftaccount. If we detect your Microsoft account, we'll show it on this screen. After you signin, your product is added to your Microsoftaccount, so that you can reinstall it later, or manage your new subscription, without a product key.

This is a one-time process that adds your new product to your Microsoftaccount. After you redeem your key, you can install Office.

If Microsoft 365 can't activate, it eventually becomes unlicensed and all editing features of Microsoft 365 are disabled. Microsoft can become unlicensed for a number of reasons. For example, if your Microsoft 365 subscription expires, you must renew your subscription to restore all features of Microsoft 365.
If Microsoft 365 was pre-installed on your new PC, you must start an Microsoft 365 Family trial or buy Microsoft 365to continue using Microsoft 365.
