Latest Message<\/th>\nTitle: Users may encounter delays or failures when sending or receiving email messages in Exchange Online<\/p>\n

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

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

Additionally, users may be unable to send email messages with attached files in any connection method of Exchange Online. Sending attachments as ZIP files allows the email messages to be delivered as expected, serving as a method by which to bypass the issue while we continue to investigate.<\/p>\n

Current status: Though we’ve deployed the fix to 95 percent of the affected environment, we’ve received continued reports of impact that indicate our fix may not have corrected this issue as expected. We’ve halted the fix deployment and are reviewing these reports to determine our next steps.<\/p>\n

Scope of impact: Any user serviced by the impacted portion of infrastructure sending or receiving some email in Exchange Online may be affected.<\/p>\n

Start time: Friday, March 7, 2025, at 5:30 PM UTC<\/p>\n

Root cause: A recent service update, intended to improve our message transport services, introduced a code issue that’s resulting in impact for a portion of service infrastructure.<\/p>\n

Next update by: Thursday, March 13, 2025, at 6:30 PM UTC<\/td>\n<\/tr>\n
