I thought Hotmail.com and Outlook.com are the same beast?

So - that means the problems we are having will spread to hotmail?

Straight from the proverbial horse's mouth (someone at MS), shared
with permission:
"We are migrating mailboxes from the current Hotmail/outlook.com
infrastructure over to Office 365. This means that migrated users
have their mail hit Hotmail's front end and then forwarded to Office
365 where it re-undergoes an authentication check, but is not
actually enforced. The original spam/non-spam verdict at Hotmail is
re-propagated through the system. If the message is subsequently
forwarded some other place, it will fail DMARC because Office 365 has
an issue where it modifies message content when forwarding ("fixes"
it up). This behavior will be changed in the Sept/Oct time frame."
