I’m considering using the Microsoft Office LTSC Professional Plus 2021 activation key for activation, and I want to know if it provides permanent activation. I’m looking for a solution that won’t expire or cause any issues down the line. Has anyone used this activation key, and does it provide a permanent solution for Office 2021?

Here’s the link I found: https://productkeysbuzz.co/microsoft-office-ltsc-professional-plus-2021-activation-key/. Does this key provide permanent activation, or is it temporary?
