We are experiencing an issue with the Microsoft Safe Links service which means you may receive a “503” error if you attempt to click on a link someone outside the organization sent to you via email.
We are working closely with Microsoft to resolve this issue as swiftly as possible. Microsoft has confirmed that this is an issue with their service impacting customers globally. We do not currently have an estimated resolution time.
We have temporarily disabled Safe Links for new, incoming email messages. We will re-enable the Safe Links service after Microsoft has solved the problem.
We will provide an update as soon as we know more. We apologize for this disruption. Thank you for your patience.
