Every time I try to enter in my product key I get a message that tells me THIS PRODUCT KEY WAS USED WITH A DIFFERENT ACCOUNT. It was not though. I need to speak to someone to get this corrected. How can I get someone to help me with this issue?

    The message means that you unfortunately bought a product key that was already used. This is an issue between you and whomever sold you that product key.

    We purchased the product key from Microsoft for our work and had it installed on our computer and about 2-4 weeks ago something happened and we got logged out or something and didn't have access. We were told by our software people that we should be able to reinstall it now, but it is not working for me.

    You can't use the product key when you reinstall. Instead, you reinstall and activate using your associated account.

    Which specific product is this, by the way? Office Home & Business 2024? Or something else?

    In particular, volume license products must be dealt with in a different way.
