Thousands of Microsoft customers reported difficulty Thursday accessing the technology company’s suite of Microsoft 365 services, including email platform Outlook, Teams and other tools. But the company said on social media early Friday that, “We’ve confirmed that impact has been resolved.”

Users started reporting problems accessing Microsoft applications on Thursday afternoon, according to Downdetector, a site tracking website outages. Complaints spiked at around 3 p.m. ET, when 16,000 people said they were having trouble accessing Microsoft 365. 

Microsoft acknowledged the problem, stating on its website that “users may be seeing degraded service functionality or be unable to access multiple Microsoft 365 services.”

At 4:14 p.m. ET, Microsoft posted on X that it had “restored the affected infrastructure to a healthy state.” In a later post, however, the company said it was still “rebalancing traffic across all affected infrastructure to ensure the environment enters into a balanced state.”

As of late Thursday afternoon, some social media users were still complaining that they were unable to access Microsoft 365 tools. “We cannot even email. This is not fixed,” one person said on X.

Other users called on Microsoft to compensate customers for the outage, which they blamed for hampering their work.

In a statement Thursday night, a Microsoft spokesperson told CBS News: “We are working to address a service functionality issue. A subset of customers may be intermittently impacted. For more information, please see updates via Microsoft 365 Status on X.”  

Verizon last week offered affected customers a $20 credit after a major service outage limited subscribers’ ability to use their wireless devices.

In 2024, a botched update of CrowdStrike antivirus software caused global outages for Microsoft 365 users. The disruptions led to thousands of flight delays and cancellations, while hospitals, banks and other businesses around the world were also affected.
