Can't send any emails from Exchange online to outlook.com

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:
