Incident Resolved

Microsoft have mitigated the issue by diverting Mail flow around the affected infrastructure. 
 
Email services should now be returning to normal, however due to the backlog of emails, it may take some time for emails to send through as per usual. 
It would also be advisable to resend emails that you have received bouncebacks on to ensure they reach their intended recipients. 
 
Kind Regards
