Global Exchange Admin Center Outage: Microsoft Investigates Critical Disruption Affecting IT Admins

Microsoft Grapples with Global Exchange Outage: What You Need to Know

A sudden and widespread service disruption is currently affecting IT administrators across the globe, as Microsoft investigates an outage that has rendered the Exchange Admin Center (EAC) inaccessible for many users. Tracked under the identifier EX1051697 on the Microsoft 365 Admin Center, the issue has been marked as a critical service incident, impacting users worldwide.

Since the outage began, administrators have encountered repeated HTTP Error 500 messages when attempting to log into the Exchange Admin Center. In response, Microsoft is actively exploring the root cause, including recent service changes that might have triggered the failure. Despite the main access point being down, some users have reported partial success using an alternative URL — `https://admin.cloud.microsoft/exchange/`.

Microsoft has acknowledged the workaround, but cautions that it is still undergoing validation. Meanwhile, internal engineers have successfully reproduced the error and are collecting additional diagnostic data to aid in identifying the core issue.

This outage comes on the heels of a series of recent Exchange-related service disruptions, including one just last month where Outlook on the web users were unable to access Exchange Online mailboxes. Another prolonged disruption caused significant delays and failures in email delivery across the platform.

The current outage underscores growing concerns over the reliability of Microsoft’s cloud services as enterprises increasingly rely on them for critical communication infrastructure.
