Update - Microsoft has provided the following update shortly after 10:45am:
"We’re seeing encouraging recovery progress, with service availability and email delivery performance improving across a growing portion of affected infrastructure... We will continue to share more information as we have it, and for now we can confirm that there is no indication this is the result of malicious or cyber activity. Our teams are reviewing what happened and how we can prevent similar issues going forward."
As email and related services begin to function normally, be aware that as Microsoft works to complete their adjustments, there may be moments of intermittent connectivity disruption or delay. While Microsoft continues to provide updates and resolves the incident, JMU IT will continue to monitor the situation and provide updates as more information becomes available.

Monitoring - Microsoft has provided the following update shortly after 7am:
"We’re seeing encouraging recovery progress in Europe, with service availability and email delivery performance improving across a growing portion of affected Microsoft 365 infrastructure. Japan remains comparatively more stable, while North America is also improving; however, some users may still experience intermittent issues as recovery actions continue. We're focused on addressing the remaining areas of disruption and improving service consistency across affected regions. Reducing email queues and backlogs remains a priority, and the extended 48-hour email timeout window remains in place to help protect delayed messages as delivery catches up."
At this time, email and calendar notifications may begin appearing and updating, however there may be an extended delay between the message being visible and/or syncing across applications. JMU IT will continue to monitor the process and update with any additional details.

Update - Microsoft has provided the following update shortly after 5am:
"We've made additional progress toward service recovery... Traffic is being gradually restored, and we're seeing improvements in key customer scenarios, including mailbox access and delayed email processing. However, some users may continue to experience intermittent issues. Our focus is now on extending these recovery actions across affected infrastructure in other regions, while continuing stabilization efforts and adding supporting capacity to improve service consistency.
At this time, we have no evidence of malicious activity associated with this incident. We will continue to treat this with urgency until full mitigation, and we will share a full Post-Incident Report with root cause and defense-in-depth actions after mitigation is complete."
As Microsoft continues to provide updates and makes adjustments, access to applications that interact with Exchange Online and email services may be intermittent or inaccessible. JMU IT would like to remind the community that the current incident does directly impact Zoom Meetings and Chat options, or Teams Chat (note that the Calendar Sync in both respected applications may be impacted). Additional updates will be posted as they are available.

Update - Microsoft has provided the following update shortly after 9pm:
"We’re applying infrastructure capacity improvements where possible in an effort to help support traffic in regions coming online. We’re continuing to monitor the results of changes applied so we can identify strategic actions that can help to improve service health across all affected regions. As a result, we’re seeing positive results with our efforts to restart affected infrastructure and recover server availability in an isolated manner. We’re actively monitoring the performance of these portions of infrastructure to verify stability, which we suspect will support improved availability as these actions are subsequently expanded more broadly."

Identified - Microsoft has provided the following update shortly after 4pm:
"We determined the elevated load isn't driven by an increase in traffic, but by a number of servers being unexpectedly unavailable; straining the remaining infrastructure... We've validated an alternative service health check method, which allowed a subset of affected servers to successfully return to service. We're now applying this change more broadly. We're also preparing automated recovery systems to continually detect and restart unresponsive servers, to maintain service stability while this change progresses."
As Microsoft continues to provide updates and makes adjustments to service, access to applications like Outlook and the ones listed may be intermittent or inaccessible. Additional updates will be posted as they are available.

Exchange Online
Microsoft Teams
SharePoint Online
Microsoft Copilot 365
Microsoft Defender XDR
