Here is my take on the positive surge for various senders ~8/16.
Looking back in the June 14-16ish range, there appeared to be a surge of
increased Spam Rates for many senders in Postmaster Tools (many

I have a reply from one of our Hotmail experts:
“Outlook.com is changing the frontdoor infra to leverages Office365 (EOP), and

We're seeing bounces as of 8/31, around 5pm eastern. It looks like
hotmail.co.uk has changed their MX records, so it's not the same as hotmail.com
anymore. If you have a config on your mta that rolls up different MS domains
into one queue, you'll need to remove hotmail.co.uk out of that config.

code:
"550 Requested action not taken: mailbox unavailable,"
That's usually reserved for invalid email addresses, but they are bouncing
100% of the messages we send them on on of our IP ranges with that code.
