Yes, I went through the same thing. I'm hosting at Linode, and they were very helpful. Generally Microsoft (hotmail, outlook, etc.) won't budge from their block unless the request comes from the owner of the IP address (Digital Ocean). Linode support did a great job for me.
Scroll through the page referenced in the error message (https://postmaster.live.com/pm/troubleshooting.aspx#errors) and find the link to the Junk Email Reporting Program and sign up with them.
Go through all the hoops.
It took me about a week. Eventually they'll take a look at the email coming from your IP address and make a decision.
It's such a pain to move an email server to a new IP address -- I lived with a machine with software that was so hopelessly out of date I couldn't update any packages, knowing I'd have to go through this when I rebuilt it on a new IP address.
Good luck! Best regards, Mojo

I have submitted a ticket to https://support.microsoft.com/en-us/supportrequestform/8ad563e3-288e-2a61-81...
Not sure why they are blocking me. Not on any other blacklists per mxtoolbox...
Anyone else experienced this? How to resolve?
My mail server is on Digital Ocean if that makes any difference.
Thanks for any help
