Hi everyone,
If you purchased a boxed version of Office, you get a product key with it. Or you may receive your product key in an email if you bought your Office 365 from an online store. This video shows step by step instructions on how to use your product key to start or renew your subscription.
If you don’t know what your product key is, see this article: Find your Office product key.
Let us know what you think of these help topics by submitting your feedback at the bottom of each article.
Thank you!
