Microsoft outage: Majority of services recovered for most users

U.S.

(NewsNation Now) — Did you have trouble logging in to Microsoft Teams or Outlook 365 Monday afternoon?

Microsoft says while the majority of services recovered for most users Monday evening, a small subset of customers in North America continued to experience issues after an outage impacted users across the country and the world earlier Monday.

Affected products include Office 365, Outlook, Teams, Azure, OneDrive and SharePoint, among others.

As of a 7:39 p.m. CDT update, Microsoft said “engineering teams have applied mitigation steps and customers in both the Azure Public and Azure Government clouds should see signs of recovery at this time.” 

In a 6:48 p.m. CDT tweet, the company said they were “rerouting traffic to alternate infrastructure to improve the user experience while we continue to investigate the issue.”

In the last update to status.office.com, Microsoft says, “We have confirmed via our monitoring that the majority of services have recovered for most customers. However, we continue to see a small subset of customers whose tenants are located in North America region who are still impacted. We’re now investigating mitigation steps for those customers who are still affected.”

Users of several different Microsoft services including Outlook and Teams started reporting problems Monday afternoon, according to website Downdetector.com.

“We’re investigating an issue affecting access to multiple Microsoft 365 services. We’re working to identify the full impact and will provide more information shortly,” Microsoft said in a tweet first acknowledging the issue.

Microsoft later followed up in a tweet saying in part, “We’ve identified a recent change that appears to be the source of the issue. We’re rolling back the change to mitigate impact,” then tweeted that after that rollback, they were “not observing an increase in successful connections.” Microsoft then said they were “working to evaluate additional mitigation solutions while we investigate the root cause.”

According to one of the series of updates posted to status.office.com, Microsoft says they found the issue is “a specific portion of our infrastructure is not processing authentication requests in a timely manner. We’re pursuing mitigation steps for this issue. In parallel, we’re rerouting traffic to alternate systems to provide further relief to the affected users.”

In a statement to NewsNation earlier Monday, a Microsoft spokesperson said: “We’re working to resolve a service interruption impacting a subset of customers performing authentication operations. Visit the Azure Status page for updates.​”

The first reports of the outage appeared to come in shortly after 4 p.m. CDT. As of 11 p.m. CDT Monday, Microsoft said “the residual issue has been addressed and the incident has been resolved. Any users still experiencing impact should be mitigated shortly.”
