Update
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.

We do not have an ETA for full recovery yet. Service access can recover before mail flow fully normalizes.
Update
Current status: 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, 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.
