I wasn’t going to add to this but one last attempt to get my point across.
I blame MS whether they’re within their ELA or not. If - and please understand me here - the key is not legitimate MS should not let it activate Office.
This would give the buyer the opportunity to get a refund from the seller as the item is "no good". Eventually trade would dry up and problem solved. By permitting the key to work at all MS are saying this is ok, then later they sabotage your program. Some of you think that’s okay. I don’t.
And Clint, out of curiously I'm buying one of those yellow stickers Office disks just to see.
