Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
If you purchased a Microsoft365 license and the seller told you its lifetime, then its probably not a genuine license. Amazon is just a marketplace with all sorts of sellers. Buyers beware.
A few clues that your license is not genuine
- Its Microsoft365, but says lifetime. xxxxx365 products are subscription based.
- It says Office Pro Plus or has LTSC in the name. These are sold in volume to corporates, not individual users
- It is 50-70% cheaper than regular Microsoft prices. Microsoft reseller makes single digit % margins only.
If you unfortunately purchased an incorrect license from a problematic seller, you don't have much of a choice than to purchase the genuine license, either from Microsoft direct, or a reputable Microsoft reseller.
