Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I would go back to you employer and ask them to resend you the Home use invite email as that should have the information. The product key comes out of the volume licensing division and thus why you are bounced around a lot.
"One Microsoft" isn't quite one Microsoft. VL is a totally separate department than consumer retail purchases.
Then they shouldn't sell me the disc under false pretenses, even including the sticker. Plus, while I was on the phone the last time, I was told that I was being transferred to thethe department that produces the Product Key and they told me that I didn't need the code even after I read it to them on the package. The whole setup is stupid. If I am not allowed access to office.com/myaccount then they should not sell me a disc with my purchase that says all I have to do is go to that account and take care of everything. Even the agents on the phone agreed that was very misleading. By all rights they should live up to there mistakes and honor the information they sent to me.
Everything I was told may be poppy-****, but that would not surprise me either.
