Latest Message<\/th>\nTitle: Some users experienced errors or failures when accessing their mailbox in one or more Exchange Online connection methods<\/p>\n

User impact: Some users experienced errors or failures when accessing their mailbox in one or more Exchange Online connection methods<\/p>\n

More info: Impact more heavily affected Outlook.com users.<\/p>\n

Final status: We\u2019ve confirmed after a period of monitoring that service availability has returned to normal levels and the backlog of messages have been processed.<\/p>\n

Scope of impact: Users attempting to access their mailbox in one or more Exchange Online connection methods may have been impacted.<\/p>\n

Start time: Tuesday, September 30, 2025 at 11:27 PM<\/p>\n

End Time: Wednesday, October 1, 2025 at 11:15 AM<\/p>\n

Preliminary root cause: A recent configuration change unexpectedly caused a portion of infrastructure responsible for processing request flow traffic to operate below expected thresholds, resulting in impact.<\/p>\n

Next steps:
– We\u2019re analyzing the configuration change to better understand the cause of the impact and to help prevent similar problems in the future.<\/p>\n

We’ll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.<\/td>\n<\/tr>\n
