Microsoft Blames Outlook Outage on Faulty Code Change
Issues Persist Into Monday, Causing Frustration for Users
Microsoft has attributed this past weekend’s widespread Outlook outage to a “problematic code change,” leaving thousands of users unable to access their email accounts.
The disruption began around 2100 UTC on Saturday, with more than 30,000 users reporting issues via DownDetector. While Microsoft claims services have since been restored, some users are still experiencing intermittent problems as the workweek kicks off.
According to Microsoft’s status page, the company swiftly identified the issue and rolled back the faulty update to “alleviate impact” while closely monitoring system telemetry.
“Following our reversion of the problematic code change, we’ve monitored service telemetry and worked with previously impacted users to confirm that service is restored,” Microsoft stated.
Ongoing Issues and Additional Downtime
Despite Microsoft’s fix, some iOS users reported persistent login failures, requiring them to delete and reinstall the Outlook app to regain access.
Adding to the frustration, Microsoft 365 services faced additional downtime on Monday, affecting users trying to connect to Teams meetings and other collaboration tools. Access remains inconsistent, with some users able to log in while others still struggle.
We’ve reached out to Microsoft for further clarification on the outages and will provide updates as more details emerge.
A Rocky Start to the Year
Microsoft’s recent service disruptions are part of a troubling pattern. In February, Azure outages impacted customers in the Nordics, and January saw widespread login failures across Microsoft 365—following yet another Azure outage just days before.
With these recurring issues, Microsoft is starting the year on shaky ground when it comes to service reliability.
