Sounds like the standard bot generated spam, but it has been mentioned
before, if posting to this list, a complete header is usually best in
order for list members to comment on.
It would help to see if this is simply an outbreak of compromised email
accounts (less likely) or some type of allowed relay.. or infrastructure
change.
Suprised that the c&c of this bot hasn't been found yet, it has been
going on a while..

We’re seeing huge amounts of spam coming from cox.net (68.230.241.0/24)
over the past few days. Going to our filtering system but also getting
through to Office 365 and Gmail accounts without any issue at all.
They are all the well written, formatted “please remit” type emails with
a Word Doc attached.
Interesting, the example I’ve had sent to me today went directly to my
users @domain.onmicrosoft.com address, so not to the custom domain. The
customer has never actually used the onmicrosoft.com domain for anything.
This is a repeat of what we saw from the same IP range in June. Anyone
at Cox.net that can comment?
Example of what we see:
*From:*Coulson, Nick [mailto:bbulla...@cox.net]
*Sent:* Wednesday, 31 August 2016 1:05 PM
*To:* Real Staff Members Name <abc....@hidden.onmicrosoft.com>

Hello Real Staff Members Name,
