Update
Our engineering team have added additional delivery ranges to mitigate the issue. Some emails are being delivered while others are being deferred. Any deferred emails will be delivered once a fix has been implemented. We are working with Microsoft on this. We will provide a further update in due course. Thank you for your patience.
