Activate Product

To continue to use all the features of Microsoft Office, you need to activate your subscription for Office. This wizard will guide you, step-by-step, through the process of activating your subscription via the Internet or over the telephone.

If you choose to activate your product through the Internet and you are not already connected, the wizard will help you get connected. If you choose to activate your product by talking to a customer service representative over the telephone, please note that it may take longer to complete the process.

If you have purchased a non-subscription version of the product and would like to install it, click the appropriate box near the bottom of the dialog and then enter the 25-character product key for the product you want to install. After installing the product, you will need to close and restart any open applications to ensure that they work properly.

What happens if you don't activate your subscription for Microsoft Office?

Before you activate your subscription, you may run Microsoft Office for a limited amount of time. Microsoft Office will go into Reduced Functionality Mode when this grace period expires. In Reduced Functionality Mode, you will not be able to save modifications to documents, or create a new document, and additional functionality may be reduced.

No existing Office files or documents will be harmed, and you can easily get Office out of this mode by following the instructions outlined in the screens presented.
