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 Premium or Office 365 University subscriptions

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

 Important    If the My Account page indicates Office isn’t associated with this account, it could mean the wrong Microsoft account was used to sign in. You’ll need to sign in with the Microsoft account that was entered when you redeemed and installed Office for the first time. If you continue to have problems signing in to My Account, please contact Microsoft support to review your options.

ShowOffice 2013 Home and Student, Office 2013 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 My Account, sign in with the Microsoft account tied to the product and use the Install button on the My Account page.

If you’d prefer to install Office using a disk and you need the product key, you can find it on your My 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 the My Account page indicates Office isn’t associated with this account, it could mean the wrong Microsoft account was used to sign in. You’ll need to sign in with the Microsoft account that was entered when you redeemed and installed Office for the first time. If you continue to have problems signing in to My Account, 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.

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.

What are my options if I can’t find my product key and I don’t have a valid proof of purchase?

  • You’re entitled to the newest version of the Office applications whenever they are available.

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.
