Users encountered specific errors, with Outlook displaying '451 4.3.2 temporary server issue' messages, hindering email communication. Downdetector, an outage tracking site, registered tens of thousands of reports, including 12,380 for Outlook, 15,745 for Microsoft 365, and 2,246 for the Microsoft Store at its peak. Microsoft attributed the problem to a portion of its North American service infrastructure not processing traffic as expected. A targeted load balancing configuration change, intended for recovery, inadvertently exacerbated the issue, leading to further traffic imbalances. This internal infrastructure challenge was distinct from a previous January 21 outage caused by a third-party network issue. #microsoftoutage #outlookoutage #microsoft #microsoftOutageToday #outlookdown #microsoftOutlookOutage #isoutlookdown #outlook #ismicrosoftdown #microsoftdown #outlookemail #microsoftEmailOutage #microsoft365Outage #isOutlookDownRightNow #outlookOutageToday hsQITo7W7X3 C6rDNn3w32x rq5bNVDZwHf rKLYhx5bKUN JTwinC2gY0o KBLGTvvOIei dWZy9RsMQao KNPCinKidq7
