Incident Report

Exclaimer engineers have identified a global issue with Azure that is impacting our ability to handle messages, as new compute resource cannot currently be created to handle demand, and as such customers in AU might experience issues with message delivery. You can look to disable the Mail flow rule ‘Identify messages to send to Exclaimer Cloud’ to restore mail flow. We will continue to monitor the performance to ensure that the service fully recovers, and provide any updates received by Microsoft. They currently anticipate the fix for this will be in place by 00:00 UTC. If you are experiencing any other issues with Exclaimer at this time, please contact our support team right away.
