Microsoft Outlook and Teams outage resolved
Thousands of users reported service issues with the Microsoft products on Thursday, a day after a brief outage happened with the same products.
Microsoft resolved an outage early Friday morning after tens of thousands of people reported issues with various products on Thursday.
More than 15,000 users reported issues using Microsoft 365 products at around 3 p.m. Eastern, according to the outage-tracking site DownDetector. Another 12,000 people reported issues with Microsoft Outlook, and 500 reported issues with Microsoft Teams.
Microsoft Support teams were investigating the outage, the company said in a social media post. Investigators blamed the issue on the service infrastructure.
"We've identified a portion of service infrastructure in North America that is not processing traffic as expected," the company said. "We're working to restore the infrastructure to a healthy state to achieve recovery. More information can be found at https://status.cloud.microsoft or under MO1221364 if accessible."
Nearly two hours after the outage began, investigators said they've restored infrastructure to a "healthy state," but said further load balancing is required to mitigate the outage's impact.
"We're directing traffic to alternate infrastructure to achieve recovery," Microsoft said in a social media post at 4:14 p.m. Eastern. "More information can be found at https://status.cloud.microsoft or under MO1221364 if accessible."
Microsoft offically announced the outage had been resolved hours later at around 1:30 a.m. Eastern, saying mail flow is stable and access to affected services has been restored.
Microsoft resolved a brief outage on Jan. 21, which investigators said was caused by a third-party networking issue. That outage only lasted just over an hour.
