How do I recover or replace a lost Microsoft Office product key?

Losing your product key can be a frustrating experience, especially if you need it to install Office. To explore options to recover or replace a lost Office product key, choose your Office version:

ShowOffice 365 Home, Office 365 Personal, or Office 365 University

You likely won’t need to recover or replace the product key if the subscription has already been redeemed. To install Office, go to your account page, sign in with the Microsoft account tied to your subscription and click the Install button.

 Important    If you sign in to your account page with a Microsoft account that’s not linked to your subscription, you’ll get this message on the page: “Office isn’t associated with this account.” You’ll need to sign in with the Microsoft account that was used when you redeemed and installed Office for the first time. If you continue to have problems signing in to your account page, please contact Microsoft support to review your options.

If you bought the box product at a store and you haven’t installed and redeemed the Office subscription yet, the product key can be found in the packaging. For more information, read Find your product key for Office 2013, Office 365 Home, Office 365 Personal, Office 365 University.

ShowOffice 2013 Home and Student, Office 2013 Home and Business, or Office 2013 Professional

You likely won’t need to recover or replace the product key if you purchased Office 2013 online or it’s been installed once before. To install Office, go to your account page, sign in with the Microsoft account tied to the product and click the Install button.

If you’d prefer to install Office using a disk and you need the product key, you can find it on your account page. Under the Account Options, click Install from a disk. On the next screen, click on I have a disk, and then click on the View your product key button to display the install product key.

 Important    If you sign in to your account page with a Microsoft account that’s not linked to your subscription, you’ll get this message: “Office isn’t associated with this account.” You’ll need to sign in with the Microsoft account that was used when you redeemed and installed Office for the first time. If you continue to have problems signing in to your account page, please contact Microsoft support to review your options.

ShowOffice 2010 Home and Student, Office 2010 Home and Business, or Office 2010 Professional

You may be able to recover the Office product key online. This option is available if you purchased, downloaded, and installed Office 2010 online or, at one point, the key was associated with a Microsoft account. To recover the product key, go to My Account and sign in with the Microsoft account tied to the install. The account details page will contain the product key and provide a download link to install Office.

You may also be able to recover the Office product key in the confirmation email you received if you purchased the product online. If you purchased Office 2010 directly from Microsoft, search for “Microsoft” in your emails. If you purchased from a third-party retailer try searching the retailer’s name. Check all mail folders including the Junk folder for this email.

If you bought the box product at a store, the product key can be found in the packaging. For more information, read Find your Product Key for Office 2010.

You can also contact Microsoft support. Support may be able to help you if you have a valid proof of purchase. If you don’t, there is very little they can do. While we understand this can be frustrating, please note that this is similar to other company or store policies when you lose your proof of purchase for their products.

ShowMicrosoft Office 2007 or earlier versions of Office

If the product key is lost, contact Microsoft support as they may be able to help if you have a valid proof of purchase. If you don’t, there is very little they can do. While we understand this can be frustrating, please note that this is similar to other company or store policies when you lose your proof of purchase for their products.

We recommend you consider purchasing an Office 365 Home or Office 365 Personal subscription. Here are the benefits if you’re an Office 365 customer with an active subscription:

  • You can sign in to your account page and install Office without the need of a product key.
  • You can install Office on up to 5 PCs or Macs, and 5 mobile devices (if you purchase Office 365 Home).
  • It enables you to install Office in a range of languages.
  • You’re entitled to the newest version of the Office applications whenever they are available.

You can also try uploading your document, workbook, or presentation to OneDrive and then opening it with an Office Online application. Office Online is free to use and while it may not provide all the features and benefits that come with an Office 365 subscription, it may help you open, edit, and print your file if you need to do something quickly. For more information about uploading files to OneDrive, go to Using Office Online in OneDrive.
