So the issue remains, what *is* the correct way to migrate to a new IP that's been blacklisted by MS and how long should it take?
As a similarly low volume sender, I've never found any real trick other than signing up for every feedback loop in sight (I get the impression that this helps them understand that it's intended to send mail, and care about the results, although who knows), then set up deliveries to use the new range first, and smarthost through your old IP when the new range fails.
Once failures start, and they will, fill out the postmaster contact forms and wait, while trying again, often you'll get nothing back or a "Look at our best practices, but we can't help" yet suddenly mail will start flowing again.
Ultimately it seems to take a month or so before delivery starts to become reliable, last I moved IPs.
This isn't just for Microsoft, but for all the big providers. Usually after a month or so, the intermittent problems stop, but in the mean time, flowing mail through the old IPs once the new ones get rejected helps keep your customers from rebelling.
