I purchased a cloud server recently and come to find out when emailing Microsoft Addresses I would get a bounce back that I was in a block list. Here are the domains in question:
hotmail.com
live.com
msn.com

First I went here to check if I was on a blacklist server and I was not:
https://mxtoolbox.com/blacklists.aspx
After some searching I found the following website to request your IP be removed:
https://support.microsoft.com/en-us/supportrequestform/8ad563e3-288e-2a61-8122-3ba03d6b8d75
My request has been submitted and I will see if that resolved the issue.
