I have had confirmation from an external company that is trying to email me that Microsoft are blocking the email from getting to my inbox. The error they get is:
"Recipient's policies restrict messages"
I have been advised to contact Microsoft support, so I opened a ticket to talk to a support agent who was unable to assist me, and advised that I spoke to a Outlook Support Agent instead, but I ahve been able to actually contact one of them as it keeps telling me that I have to get community help with my problem.
I appear to be having the same issue as the user in this post:

Any ideas on how I can actually get this resolved?
