Exchange Admin Center Not Working? Microsoft Confirms 'Internal Server Error'

Microsoft Exchange administrators are running into trouble accessing the Exchange admin center (EAC), with some users encountering an “Internal Server Error.” Microsoft has acknowledged the issue and is rolling back a recent change while investigating the cause.

Microsoft is rolling back a recent Exchange Admin Center change

In an update posted on X, Microsoft 365 Status confirmed that some administrators may be unable to access the Exchange admin center. The company directed affected admins to incident EX1500900 for more information through the Microsoft 365 admin center.

The problem appears to affect access to the EAC rather than confirming a wider Exchange Online outage. Microsoft has not yet shared the full scope of the disruption or identified the precise cause.

Notably, the company has already started rolling back a recent change to the Exchange admin center. Microsoft says the rollback should help determine whether the change is responsible for the reported impact.

Microsoft continues investigating the source of the outage

Microsoft is closely monitoring the situation to check whether the rollback improves access. However, the company has not confirmed that the issue is resolved, and its investigation remains ongoing. Admins experiencing the error can check incident EX1500900 through the Microsoft 365 admin center.

For now, affected administrators may need to wait for Microsoft’s next update. There is no confirmed timeline for a full resolution, and the company has yet to disclose additional troubleshooting steps. We will update this story as Microsoft shares more details about the Exchange admin center disruption.
