How can I get in touch with a natural person? -- Activation issues

Please provide full details on the problems you are experiencing, is that with a Microsoft Office instalaltion, or something else, and please provide a screenshot of any error you may be seeing.

I have an Office 2021 key which has been working very well since 2023, I have just reinstalled the PC following a hard drive crash and when I enter this key I get an installation id I have a message which says that the activation is not valid without knowing what I should do.

Hello Cécile GAUDIO,

Welcome to Microsoft Q&A.

I understand you're trying to activate Office 2021 after reinstalling your PC and are seeing a message that the activation is not valid.

When a PC is wiped or the hard drive is changed, it might trigger reactivation issues. Office activation is tied to both your hardware profile and your Microsoft account. If the system detects a significant change, it may treat the device as new and reject the activation attempt.

That said, the core issue here is not just the hardware change: you only need the key once. Once you redeem your Office 2021 product key at https://setup.office.com, it becomes permanently linked to your Microsoft account. From that moment on, your Microsoft account becomes the anchor for reinstalling and activating Office and the key itself is no longer used for activation. This is why entering the key again does not work.

So, rather than entering the key again, simply sign in to your Microsoft account that is used to redeem the subscription, and Office should activate automatically. If it does not, go to https://account.microsoft.com/services, sign in with the same account, and reinstall Office from there.

I hope this helps clarify things. If you have any further questions, feel free to ask.

Warm regards,

If you reinstalled Office using the original account, sometimes (re-)activation is automatic. In cases when it is not, you have to contact Microsoft support for assistance with activation.
