Microsoft said Thursday it was investigating a OneDrive outage that’s leaving some users unable to access the cloud file storage service.
On Thursday afternoon, a OneDrive sign-in page viewed by CRN displayed the message, “Sorry, an error has occurred.” As of this writing, the OneDrive outage appears to be continuing to affect the cloud-based service for some users.

It is the second major outage to affect a Microsoft 365 service this week, following issues that affected users of the cloud-based Microsoft productivity and collaboration applications on Monday and again on Tuesday.
On Thursday, Microsoft acknowledged on its service health status website that an unspecified number of OneDrive users “may be unable to access the OneDrive service.”ADVERTISEMENT
“We’ve reviewing OneDrive telemetry that captures this impact scenario to determine the source of the service access failures and begin identifying a mitigation plan,” Microsoft said on the page.
In an update at 3 p.m. ET Thursday, Microsoft said it is “continuing to analyze monitoring telemetry and performing load-balancing processes to provide relief.”
A subsequent update to the status page Thursday indicated that the outage has only impacted access to OneDrive through a web browser. “Access to the OneDrive service using the desktop client, a synchronization client or Office clients are not impacted,” Microsoft said in the update.
Hactivist Claims
According to a BleepingComputer report Thursday, a hacktivist group known as “Anonymous Sudan” has claimed responsibility for causing the OneDrive outage, via a post on Telegram. The group also reportedly said it had carried out DDoS (distributed denial-of-service) attacks against Microsoft services earlier this week.
“We are aware of these claims and are investigating,” Microsoft said in a statement to CRN Thursday, in response to a question about the hacktivist group’s claim. “We are taking the necessary steps to protect customers and ensure the stability of our services.”
On Monday, Redmond, Wash.-based Microsoft said that services including Teams, SharePoint Online and OneDrive for Business were affected by service issues. The following day, the company said it was experiencing a “recurrence of the issue and a drop in service availability.”LEARN MORE: Cybersecurity | Cloud Platforms | Cloud Software
