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: We expect the impact to be mitigated for a majority of our users; however, we remain focused on ensuring this incident is fully resolved.<\/p>\n

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 investigating a change to background caching logic as a potential underlying cause of impact. While our current mitigations have effectively eliminated the impact from this issue, we\u2019re creating an additional change to address the underlying problem, which is expected to completely remediate the issue. We\u2019ll continue to provide updates on the build progress and closely monitor the service environment. <\/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
