Résumé détaillé

A Microsoft outage involving services like Outlook and Teams has dragged on for hours and impacted many users, companies and some government operations as the tech giant struggles to fix the issue.

From Asia to the U.S., a Microsoft 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 struggles to fix the issue.

Microsoft said in an update early 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 didn't have any indication that the outage was caused by malicious activity and would treat the incident "with urgency and priority until full resolution."

More than 130,000 users on outage tracker Downdetector reported problems accessing Outlook earlier on Thursday although new reports have since fallen from that peak.

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.

In its latest update, Microsoft said, "Recovery actions are ongoing and have progressed in phases across affected Microsoft 365 infrastructure. ... However, service health remains variable and capacity has not yet fully returned to baseline."

OpenAI and Anthropic each reported that they were facing problems connecting with Microsoft 365 tools, underscoring the ripple effects of outages as more people use artificial intelligence platforms to interact with other companies' software.

U.S.-based industrial technology company Workhorse Group Inc. delayed a conference call on its quarterly earnings because of the outage.
