Update - Current status from Microsoft: As infrastructure stabilizes, we're still draining queued messages and rebalancing traffic, so customers may see improved sign-in/access while delivery and processing continue to catch up. We do not have an ETA for full recovery yet. Service access can recover before mail flow fully normalizes.

Update - from Microsoft:

We’re seeing continued recovery progress across affected regions, with broader improvements now observed in North America and sustained improvements across much of Europe. We’re also seeing encouraging recovery signals in Asia Pacific, although some users may continue to experience intermittent access issues or delayed email delivery as mitigation progresses across the remaining affected infrastructure.

Our focus remains on stabilizing recovered infrastructure, completing mitigation in the remaining impacted areas, and reducing delayed email queues and backlogs. We’re closely monitoring service consistency and validating recovery across different connection methods as we work toward full mitigation.

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.

Cetrom is continuing to monitor the issue closely and will continue to provide updates. If you are still experiencing issues accessing email this morning, you can also access those at spam.cetrom.net.

Thank you for your patience while Microsoft works to fully resolve this issue,

Update - Here is the most recent update from Microsoft:

Current status: Recovery actions are ongoing and have progressed in phases across affected Microsoft 365 infrastructure. Global telemetry and customer reports show incremental improvement in several workloads; however, service health remains variable and capacity has not yet fully returned to baseline.

Network and traffic-management actions remain active. To protect email during recovery, we’re continuing to prioritize queue and backlog processing, and the email timeout window has been extended to 48 hours to preserve delayed messages.
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.

Cetrom is continuing to monitor for any further issues. If you are continuing to experience issues receiving email in Outlook, you can access spooled email at spam.cetrom.net.
