Hi @Hautbout, Richard,

Thank you for posting. To help narrow down the cause of the "Network Error" message in the Exchange Admin Center, could you provide a bit more information?

What is the exact error message shown on the screen? A screenshot (with any personal information removed) may help.
Have you tried accessing the Exchange Admin Center using an InPrivate/Incognito browser window?
Have you tried clearing the browser cache and cookies and then signing in again?
Does the issue occur in multiple browsers (for example, Edge and Chrome)?
If this is a work or school account, are other admins in your organization able to access the Exchange Admin Center successfully, or does the issue affect only your account?

The answers to these questions should help identify whether this is related to the browser, account permissions, a temporary service issue, or something specific to your environment.

Thank you again for your time and understanding. I really appreciate your patience, and I’m here to help. Looking forward to your response.

Hi @Hautbout, Richard,

Thank you for providing the screenshot.

Based on the screenshot, this is the interface shown when a regular user account without administrative roles (such as Global Administrator, Exchange Administrator, etc.) accesses the Exchange Admin Center.

Before proceeding further, could you confirm whether you have already tried the troubleshooting steps mentioned earlier, including:

Accessing the Exchange Admin Center in an InPrivate/Incognito browser window

Clearing the browser cache and cookies

Testing with a different browser

Checking whether the issue affects only your account or other admins as well

I tested access to the Exchange Admin Center on my side and it is working normally.

If you have already tried those steps and the issue persists, I would strongly recommend opening a support ticket with Microsoft. A support engineer can review the affected account, verify the assigned administrative roles, check backend configurations, and perform any necessary diagnostics. Since this may require access to tenant-specific logs and internal tools, raising a service request is the most effective way to investigate further.

The Global Administrator should create a service request with Microsoft support. For detailed instructions, please refer to Get support - Microsoft 365 admin.

If you're unsure who the Global Administrator is within your organization, you can find guidance here: How do I find my Microsoft 365 admin? - Microsoft Support.

Please note that this is a user-to-user community forum. As a community user, I don't have access to tenant data, service logs, backend diagnostics, or engineering tools. Issues involving account permissions, role assignments, synchronization, or other backend services can only be fully investigated by Microsoft's support and engineering teams.

Thank you for your understanding, and I look forward to your update.
