I have Office 365 E5 and Enterprise mobility + security E5 subscriptions,
whenever i go to outlook web or use the outlook email client UWP app on Windows 10 to send an email from my Office 365 account to my personal email address (@outlook.com), i get this error after 1 second of hitting the send button:

I checked, there is no restricted users in the thread management of Office 365 admin center.
it would be weird if there was one, this is a new Office 365 subscription and account, no malicious activity has happened, it was the First email that was blocked by that message.
