Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi, @Tezza
Thank you for letting me know and sharing the screenshot.
Since Office Home 2024 is not appearing under your Microsoft account and the key is already showing that it has reached its activation limit, I recommend contacting the seller’s support team directly.
One possibility is that the key supplied is not a normal retail Office 2024 key, but a volume-license key or another type of key with a limited number of activations. Those keys are not normally intended to be sold as individual consumer licenses.
The seller should be able to confirm exactly what type of license they supplied and, if necessary, provide a proper retail replacement key.
Thanks!
