From The Verge: Some Microsoft services, including Outlook, Office 365, and Microsoft Teams, experienced a multi-hour outage on Monday, but the issues have been resolved, according to the company.
“We’ve confirmed that the residual issue has been addressed and the incident has been resolved,” Microsoft tweeted at 12AM ET on Tuesday. “Any users still experiencing impact should be mitigated shortly.”
The company first acknowledged issues at 5:44PM ET via the Microsoft 365 Status Twitter account, and said it had rolled back a change thought to be the cause of the issue at 6:36PM ET. But just 13 minutes later, the company tweeted again to say that it was “not observing an increase in successful connections after rolling back a recent change.” Microsoft tweeted that services were mostly back at 10:20PM ET.
Microsoft’s Azure Active Directory service was also experiencing issues on Monday, but the company said those were “now mitigated” as of 11:21PM ET Monday night. Microsoft said the problems were caused by a configuration change to a backend storage layer, which the company rolled back.
Update, September 29th, 11:20AM ET: Updated to confirm Microsoft has resolved the issues. The headline has also been updated to reflect this fact.
