Update: Microsoft Exchange Online Service Degradation Ongoing
Update: Microsoft Exchange Online Service Degradation and Recovery Progress
Microsoft has reported improvements in service stability and capacity as recovery efforts continue. However, the Exchange Online incident remains ongoing, and some customers may still experience intermittent disruptions or email delivery delays.
On our side, we have implemented an alternative delivery path for non-Microsoft email services. Email flow is recovering, and previously delayed messages are gradually being processed and released.
Microsoft 365 customers may continue to experience delays while Microsoft restores full service. Affected messages will continue to be retried within their configured retry period.
We continue to monitor the recovery process and work to minimize the impact.

Microsoft’s Exchange Online service degradation remains ongoing.
We have implemented an alternative delivery path for non-Microsoft email services to minimize the impact. Delayed messages are expected to be released, and normal email flow should gradually resume for these customers.
Microsoft 365 customers may continue to experience delays until Microsoft resolves the underlying issue. Affected messages will continue to be retried within their configured retry period.
We continue to monitor the situation and work to minimize the impact.

Microsoft Incident ID: EX1550543
We will continue monitoring the situation and provide updates as necessary.
Our engineering team has restored normal message processing, and the backlog of previously delayed emails has been significantly reduced and continues to drain.
We are actively monitoring the service to ensure continued stability and complete processing of the remaining delayed messages.
No new email processing delays are currently being observed.
identified
We are aware of an issue affecting email scanning and delivery times in the US region.
The issue was triggered by a temporary network connectivity disruption that caused a significant backlog in our email processing infrastructure.
The initial disruption has subsided, and our systems are recovering. However, some customers may continue to experience delays as we process the accumulated backlog.
Our engineering team is actively monitoring the recovery and working to restore normal processing times.
We will provide further updates as progress is made.
