Latest Message<\/th>\nTitle: Some users may encounter Non-Delivery Report (NDR) failures when sending or receiving email messages<\/p>\n

User impact: Some users may encounter NDR failures when sending or receiving email messages in Exchange Online.<\/p>\n

More info: Users may receive a Non-Delivery Report (NDR) containing an error stating “554 5.6.0 Corrupt message content”.<\/p>\n

Additionally, users may intermittently receive calendar invite emails as a plain text message containing winmail.dat attachments.<\/p>\n

Users may be able to send affected messages by attempting to resend. This may not be effective for all users.<\/p>\n

Current status: We’ve expanded deploying our potential fix to our entire internal infrastructure and continue to monitor targeted restarts of machines with the fix to ensure relief is resilient. Concurrently, we’ve deployed updates to our tooling that provide us with additional telemetry which we’re using with additional NDR trace data to continue to investigate and provide a more detailed diagnosis of the root cause.<\/p>\n

Scope of impact: Some users serviced by the impacted portion of infrastructure sending or receiving email in Exchange Online may be affected, although impact is limited to a small subset of messages.<\/p>\n

Start time: Sunday, March 9, 2025, at 12:07 PM UTC<\/p>\n
