Microsoft investigates outage affecting Microsoft 365 admin center

Microsoft is investigating an ongoing outage blocking Microsoft 365 administrators with business or enterprise subscriptions from accessing the admin center.

While the company has yet to disclose which regions are currently affected by this ongoing service degradation issue, it’s currently tracking it on its official service health status page to provide impacted organizations with access to up-to-date information.

“Microsoft is investigating a potential issue that may be preventing administrators from accessing the Microsoft 365 admin center,” the company explains.

“Information about this issue is posted on this page because Microsoft 365 administrators may be unable to access the admin center to get Service health information.”

This is the second time this week that Remond has had to mitigate an issue blocking access to the Microsoft 365 admin center, with the company confirming another similar incident on Thursday, following customer reports of server errors when trying to connect to the portal.

As the company revealed on Wednesday in an incident alert (MO1120879) seen by BleepingComputer, affected admins were encountering a ‘Runtime Error’ that was preventing access.

“Any admin served through the affected section of service infrastructure in the Eastern US region attempting to access the Microsoft 365 admin center may have been unable to do so,” Microsoft said.

“A portion of regional service infrastructure responsible for access wasn’t performing at the expected thresholds, and as a result impact occurred.”

In January, Redmond mitigated another outage, tagged as a critical service issue, that blocked login attempts and prevented users and administrators from accessing certain Microsoft 365 services and the admin center.

One month earlier, a Microsoft 365 outage took down the Office web apps and the admin center, causing customers to see “We’re experiencing a service outage” messages when attempting to access their Microsoft 365 apps via a web browser.
