How many devices can one key activate?

No. We sell the key only, without access to Microsoft’s Volume Licensing Service Center.

We recommend that someone from IT activates it.
Is Office 2021 Professional Plus MAK still supported by Microsoft?

Questions about this license
How fast do I get my key?
Right away: we email you a secure link to your license as soon as your payment is confirmed. It also appears in your account.
How long do I have to activate it?
There is no rush: your key waits safely until you reveal it, even months later. Once you reveal it, you have 30 days to use all its activations. Each activation you use in time is covered for life, on the computer where you activated it. MAK Volume Licenses use one activation per computer: if you later reinstall the software or the operating system, or change the computer's hardware, activating again uses another of the activations you bought, and our warranty doesn't cover it.
