Microsoft investigates Microsoft 365 outage affecting users, admins
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 block login attempts and impact Microsoft 365 suite websites and Outlook services.
“Further information can be found at https://status.cloud.microsoft, 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.
According to Microsoft, the list of likely affected services includes:
- SharePoint Online search and site or file access
- Exchange Online mailbox search or access
- Microsoft 365 Admin Center access
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 shut down the Office web apps and the admin center, and earlier this month, a Multi-Factor Authentication (MFA) outage prevented customers from accessing Microsoft 365 Office apps.
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.”
Update January 29, 14:44 EST: Microsoft updated the M365 Admin Center to say the incident has been mitigated.
“After further investigation, we confirmed that impact was limited to admins attempting to access the Microsoft 365 admin center, and we’ve updated the Title, User impact, and Scope of impact sections of this communication accordingly,” it stated.
“We’ve identified a recent configuration change that contained an error, which prevented access requests from completing as expected. We reverted this change and after a period of extended monitoring, we’ve confirmed that the issue is resolved for all users.”
