My product key isn't working
First, make sure that you're entering the key correctly on the right site. If you aren't sure which site to use, you can enter your product key using the Virtual support agent (English only). If your product key is valid, the Virtual support agent provides a link to download Office. The Virtual support agent can also let you know if your product key has been blocked and can connect you to a live agent.
If your Office product key doesn’t work, or has stopped working, you should contact the seller and request a refund. If you bought a product key separate from the software, it’s very possible the product key was stolen or otherwise fraudulently obtained, and subsequently blocked for use. Unfortunately, there are many dishonest sellers who offer stolen, abused, or otherwise unauthorized Microsoft product keys for sale. Sometimes these product keys are printed on counterfeit labels or cards with a download link to Microsoft software, and sometimes they’re distributed with software media that is unauthorized for resale, such as promotional media, original equipment manufacturer reinstallation media, or other Microsoft program-specific media.
