From Asia to the US, Microsoft’s outage involving services like Outlook and Teams has dragged on for hours and impacted many users, companies and some government operations as the technology giant struggled to fix the issue.
Microsoft said in an update Friday that the outage was affecting a wide range of Microsoft 365 offerings that interact with its Exchange Online and email services. Services including Outlook, Teams and AI assistant Copilot were reported by users to be down.
The Redmond, Washington-based company said it was trying different ways to identify the cause of the problem and get its servers back online, using “a measured approach to identify and repair affected infrastructure.”
The company said it did not have any indication that the outage was caused by malicious activity and would treat the incident “with urgency and priority until full resolution.”
Over 430 million people use Microsoft 365 apps, Microsoft said on its website.
Roughly 130,000 users from dozens of countries reported problems accessing Outlook on the outage tracker Downdetector on Thursday, although reports have since declined.
A series of posts by the company on X suggested its engineers were struggling to get the problem fully under control.
Hours after saying it managed to successfully restore service health and functionality, the company said it had updated its list of impacted services and was continuing to address the issue.
Its most recent post offered little hope for users expecting a quick resolution.
“We’ve monitored the status of the changes applied to improve serviceability and confirmed they’re not taking as expected,” the company wrote.
In a more recent update Friday, Microsoft said “we’re seeing early stabilization and capacity improvements as recovery actions continue.”
US.-based industrial technology company Workhorse Group Inc. delayed a conference call for its quarterly earnings because of the outage.
In Australia, Home Affairs Minister Tony Burke said Friday Microsoft had likened the widespread outage to the CrowdStrike outage in 2024.
Burke said he had spoken to Microsoft’s top executive in Australia and the government’s national cybersecurity coordinator about the global disruption.
“They (Microsoft) don’t believe they are dealing with a cyberattack. They believe that they are dealing in some ways (with something) similar to what we saw with respect to CrowdStrike where there is an update that has gone awry,” Burke told reporters in Sydney.
In July 2024, a massive global tech outage grounded flights, disrupted hospitals, banks and retailers, with Texas-based cybersecurity firm CrowdStrike blaming a faulty update to computers running Microsoft Windows that allowed its systems to push bad data out to millions of customer machines.
Hong Kong businessperson Danny Lau, who runs an aluminum firm, said his company’s Outlook accounts could not receive updates from their U.S. customers due to the outage. If the situation dragged on further, this could “impact the production timeline,” he said. Some banks in Hong Kong, an Asian financial hub, also saw part of their operations disrupted.
