Microsoft Case: 7016347354
We are aware of an intermittent issue whereby some users might be unable to send mails to Microsoft related email domains such as Hotmail, Live and Outlook. The cause of the issue is under investigation with Microsoft but we believe it is related to rate limiting rather than the blocking of our IPs.
Final Update:- 21/04/2023 14:00:00 PM– Microsoft have removed any rate limiting on our servers. We have been monitoring and can see all mails being successfully delivered as normal.
Thank you for your patience whilst we worked to resolve this issue.
