Microsoft Office 365 Email Outage

We are currently investigating an issue affecting the ability to setup new accounts or log in to Microsoft Office 365 webmail and email applications in all regions.

Microsoft has identified this issue as impacting Office 365 globally. Updates are being provided by Microsoft via their status page: https://status.cloud.microsoft/m365/referrer=serviceStatusRedirect . Our phone representatives do not have additional information on this issue and we are unable to take phone calls at this time. Thank you for your patience.

Microsoft is continuing to work on a fix for this issue.

Microsoft's investigation has found that a process on the affected servers responsible for establishing secure connections becomes overwhelmed, causing the servers to stop processing requests. Microsoft is preparing a configuration change to address this behavior that can be applied across all affected servers, and they're validating it on a subset of servers before applying it more broadly alongside restarts of the affected infrastructure. In parallel, Microsoft begun reverting a recent network configuration change that correlates with the start of impact and are monitoring to determine whether this contributes to recovery. The temporary traffic limitations Microsoft previously described at https://status.cloud.microsoft/m365/referrer=serviceStatusRedirect are now in effect in specific locations. They are monitoring the affected servers in those locations to confirm whether they remain stable while handling a narrower set of connections, after which they'll gradually reintroduce additional traffic.

Microsoft made additional progress toward service recovery, with recovery actions completed across portions of the affected infrastructure in different regions. Traffic is being gradually restored, and they’re seeing improvements in key customer scenarios, including mailbox access and delayed email processing. However, some users may continue to experience intermittent issues.
