Microsoft is facing a major outage affecting Microsoft Outlook. Users across the world are reporting login problems and service disruptions.
The issue started a few hours ago and quickly escalated, with thousands of users unable to access their emails. Reports on outage tracking platforms showed a sharp spike, indicating a widespread problem.
According to Microsoft’s official updates, users may experience intermittent sign-in failures. Some are seeing “too many requests” errors, while others are getting signed out unexpectedly. The issue appears to be limited to Outlook, which means other services like Microsoft Teams are still working normally.
Microsoft has confirmed that the issue may be linked to a recent service change. The company initially tried reverting the change, but that did not immediately fix the problem.
Later, Microsoft said it is investigating unusual error patterns and authentication key failures. The company is also running internal tests to reproduce the issue and identify the root cause.
There are signs that the situation may be improving. Reports on outage tracking platforms have started to decline slightly, suggesting that the impact is reducing.
Microsoft has also confirmed that it is testing a rollback of the recent change again while continuing its investigation.
