Windows 10: How do I find my product/license key for my Microsoft Office Professional Plus 2021?

I purchased Microsoft Office Professional Plus 2021 online in December 2021 and installed it on a local computer. This was a third-party purchase and not directly from Microsoft. I cannot for the life of me find my license and/or product key to re-install these products on a new computer. Is there any way to recover they license and/or keys I need so I can move my applications to my new computer?

Product Key Code for Microsoft Office Professional Plus 2016

If you can't find the product key with those programs and its displaying a list of BBBB's instead, then the key is encrypted.

How did you obtain your Office Professional Plus license?

 

Discounted Office Professional Plus for sale online

Eight years ago I obtained a copy of Office Professional Plus 2010 for a non-profit organization I work with. I bought it from a company this is authorized by Microsoft to distriubte volume license software. When I logged onto the Microsoft Volume Licensing Service Center I was given the following:

• Link to download Office Professional Plus 2010 installation file
• MAK Product Key for volume license

Types of product keys

• MAK Product Key - Allows one time activation with a Microsoft activation server
• KMS Product Key - Allows multiple activations through a companies own activation servers

Note when you buy Office through the volume license channel you are actually buying activations. No matter how many activations you buy you only get one Product Key for all of them. You get to use the same Product Key to install Office until you exceed the number of activations purchased.

I see a number of online websites that offer Office Professional Plus 2016 and 2019 for sale at a greatly discounted price. Since these products are only normally supposed to be available through the volume license channel where are these products coming from?

Suggested scenario:

These keys may have been bought originally through the volume license channel but are being resold online. For example suppose an online seller obtained 100 activations from some company. They then sell the same MAK Product Key up to 100 times to different buyers.

Does this scenario make sense? Would that explain how these copies of Office are being sold?
