Intermittent issues delivering to Microsoft 365


We've now resolved the incident. Thanks for your patience.


Office 365 connections appear to be recovering. The queues are clearing and we are monitoring the situation.


We are seeing some intermittent issues from the Office 365 end that are causing some delay in delivering email. This issue isn't with our service, but is affecting customers as we cannot deliver the email in a timely manner. No email is being lost as it's all held in our queue, and we are retrying delivery regularly.
