Microsoft is investigating an ongoing outage preventing users and admins from accessing some Microsoft 365 services and the admin center.
According to thousands of reports from affected customers logged by DownDetector, these ongoing issues impact Microsoft 365 suite websites, Outlook services, and block login attempts.
“Further information can be found at or under MO991872 if the admin center is accessible to you,” the company said.
“We’re investigating reports of an issue where some users and admins may be unable to access Microsoft 365 services or the Microsoft 365 admin center,” explains the Microsoft 365 Admin Center message.
While the company has yet to provide more information on the number of users affected by this outage and its extent, these problems are tagged as an “incident” described by Microsoft as “critical service issues, typically involving noticeable user impact.”
In December, a Microsoft 365 outage took down the Office web apps and the admin center, while a Multi-Factor Authentication (MFA) outage blocked customers from accessing Microsoft 365 Office apps earlier this month.
In November, another Microsoft 365 outage affected multiple services and features worldwide, including Microsoft Teams, Exchange Online, SharePoint Online, OneDrive, Purview, Copilot, and Outlook Web and Desktop.
Update January 29, 13:44 EST: Microsoft says it received reports that these ongoing issues have been resolved for some users.
“We’re analyzing available service telemetry to identify why the issue initially occurred and we’re also working to identify whether additional actions are required to resolve the impact for all users.”
