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 email messages 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’re closely monitoring the propagation of the fix, which remains steadily on track with our original estimation towards full saturation. In addition, our telemetry aligns with the fix path and continues to show improvement in the error rate trajectory.<\/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
