“We’re aggressively pursuing all pathways to reduce impact,” the company wrote in an update to users. “As a precaution, we’ve paused all deployments and configuration changes while we review recent changes for any correlation to this event. We’ve also moved traffic for some services off the affected infrastructure to further reduce load, with additional traffic moves in progress.”
In addition to the updates from Microsoft itself, Downdetector shows sharply elevated user reports for the following Microsoft services:
-
Microsoft Teams
-
Microsoft Outlook
-
Microsoft Copilot AI
-
Microsoft 365
-
Microsoft Azure

While the initial update indicated the outage was impacting email inboxes “in the Americas,” later updates confirmed that other regions and products were also being impacted.
An update posted at 1:07 p.m. ET stated: “We’ve confirmed the issue may affect Microsoft 365 service connectivity for users in any region, more information will be provided in the Microsoft 365 admin center under EX1550543.” The company added, “We’ve begun redistributing connection traffic across our broader worldwide infrastructure to help balance the load.”
The problem was so severe that some customers may not be able to access the Microsoft 365 admin center at all, as the company wrote on X that users should instead refer to the Microsoft service status webpage. However, this page was also down for part of the day, according to multiple Mashable reporters.
In the most recent update, posted at 2:50 p.m. ET, the company said it was “testing a configuration change to address a problem that’s causing servers to fail automated health checks and become unavailable.” The company said it is also restarting affected servers in an attempt to restore service.
Mashable contacted Microsoft with questions about the outage, and we’ll update this story if we receive a response.
