We're currently experiencing some deliverability issues to Microsoft-hosted email addresses (i.e. Hotmail, Outlook & Live.com).

This is due to Microsoft taking issue with the IP addresses used by our email service provider, who is working to resolve the situation.

As a result of this our systems have automatically and temporarily paused sending email to those addresses.

Organisations impacted by this will have sent email on the 25th, 26th, or 27th.

Email addresses which are showing as Rejected as a result of this should be lifted automatically after about 3 days; many already are.

The issue appears to be continuing for messages sent on the 28th or 29th.

Contacts impacted by this will show as as a Rejection, which will expire automatically about 3 days after message send.

Our service provider is aware of the issue and working to resolve it, but we don't have a timeframe yet.

Our service partner informs us that this issue has now been resolved.

The last of the rejections should expire today or in the coming days.

Our email service partner has identified a recurrence of the issue.

We've been informed that this is now fully resolved.
