The common thread appears to be that they are sent from gmail addresses. It could be that they are using a tool like Gmass (https://www.gmass.co/) that lets you send bulk email from Gmail by batching them in groups of 500 per day. Mail originating from Gmail must have a lower spam flag rate.
The best are the ones with 87 people on the TO: line with alphabetically increasing box names (username@). Often the set continues right into the CC: line as well.
I cannot conceive of any legit use case that would result in that pattern, which it appears both O365 and Gmail are fine with.
