AADSTS5000228: Access to tenant is denied in Power BI, Microsoft Entra, and Microsoft 365 Admin Center

Zeel Patel 5

Dear Microsoft Support Team,

I am reaching out to seek assistance regarding a persistent sign-in and tenant access issue that I am experiencing with Microsoft Power BI and Microsoft Entra ID.

I created a new Microsoft Fabric/Power BI Free tenant for learning and educational purposes. I am the only user and administrator associated with this tenant.

When I try to sign in to Power BI Desktop using my Microsoft account associated with the newly created onmicrosoft.com tenant, my password is accepted successfully. However, immediately after authentication, I receive the following error:

“AADSTS5000228: Access to tenant is denied. Please contact your administrator.”

I have also tried accessing the Microsoft Entra Admin Center directly. However, I receive the same AADSTS5000228 error stating that access to the tenant is denied.

To further investigate the issue, I also attempted to access the Microsoft 365 Admin Center using the same account. Instead of opening the Admin Center, I receive:

“HTTP ERROR 401 – This page isn't working.”

Because I am unable to access Microsoft Entra or the Microsoft 365 Admin Center, I cannot verify the tenant configuration, check Power BI service availability, assign a Power BI license, or review any relevant tenant settings.

I have already verified that my password is working because the authentication process accepts my password before displaying the tenant access error.

I have also tried signing in through different Microsoft services, but the issue continues. The problem is therefore not limited to Power BI Desktop.

Based on the behavior, it appears that there may be an issue with access to or provisioning of my newly created Microsoft Entra tenant.

I would greatly appreciate your assistance in investigating the tenant and determining why access is being denied.

Specifically, I would like assistance with the following:

Please confirm why AADSTS5000228 is being returned for my tenant.
Please verify whether my newly created tenant has been correctly provisioned and is active.
Please confirm whether the tenant or my administrator account has any restriction preventing access.
Please advise whether Power BI/Fabric can be enabled for this tenant.
Since I am currently unable to access the Microsoft Entra Admin Center or Microsoft 365 Admin Center, please advise how I can restore administrator access.
If administrator recovery or tenant recovery is required, please guide me through the appropriate Microsoft recovery process.

This tenant was created specifically for learning and educational purposes, and I would like to continue learning and using Power BI without creating unnecessary additional tenants.

I can provide the Request ID, Correlation ID, Timestamp, and other diagnostic information shown in the error message if required.

Thank you very much for your time and assistance. I would appreciate any guidance you can provide to restore access to my tenant.

Warm regards,

Dear @Zeel Patel

Thank you for providing the detailed information.

Based on the behavior you described, I do not believe this is primarily a Power BI Desktop or password issue. Since your credentials are accepted but AADSTS5000228: “Access to tenant is denied” occurs when accessing multiple Microsoft services, including Microsoft Entra, the issue appears to be at the tenant level.

As a first check, please try signing in using the original administrator account in a private/incognito browser session and make sure you are selecting the work or school account associated with the onmicrosoft.com tenant rather than your personal Microsoft account.

If AADSTS5000228 still occurs, I would like to narrow down the tenant status before recommending further troubleshooting. Could you please confirm:

Approximately when was this tenant created, and were you ever able to successfully access the Microsoft Entra Admin Center after creating it?
Was the tenant created directly through Microsoft Fabric/Power BI Free signup, or through another Microsoft service/trial?
Do you have any other administrator account in this tenant that can successfully sign in?
Does the error occur when signing in directly with the @onmicrosoft.com administrator account?

If you are the only administrator and cannot access either Microsoft Entra or the Microsoft 365 Admin Center, I recommend contacting Microsoft Support because this may require Microsoft to check the tenant status from the backend. You can also use Microsoft's official phone support guidance: Contact Microsoft Support by phone

When contacting Microsoft, I recommend clearly explaining:

“I am the only administrator of a newly created Microsoft Entra/Fabric tenant. My credentials are accepted, but I receive AADSTS5000228 – Access to tenant is denied. I also cannot access the Microsoft Entra Admin Center or Microsoft 365 Admin Center. Please check whether my tenant is active/provisioned correctly and whether tenant recovery or escalation is required.”

Have your tenant/onmicrosoft.com domain, Request ID, Correlation ID, timestamp, and error code available so the support engineer can investigate the affected tenant.

If standard support cannot resolve the tenant access problem, ask whether the case needs to be escalated to the appropriate tenant recovery/Data Protection team.

As an Independent Advisor in the Microsoft Q&A community, I do not have backend access to inspect, activate, or unblock your tenant, so Microsoft Support would need to perform any tenant-level investigation.

If it's not working, please follow this link to create a trial tenant after that you will be able to access to Microsoft 365 Admin Center to raise the ticket

Assuming that you have already created an account after registering a free trial and you can go to Microsoft 365 admin center and click "Help & support" icon to raise your ticket.

Please mention that you are raising ticket on behalf of the affected tenant that you do not have access to.

On the other hand, if you do create the trial and it resolves the issue, please remember to cancel the subscription afterward to avoid any related charges.

I hope this helps you reach the appropriate team without creating another tenant unnecessarily.

Dear BabybooHN,

Thank you for your guidance. I have never been able to access the Microsoft Entra Admin Center successfully since creating my Fabric/Power BI tenant. The AADSTS5000228 error has prevented me from accessing the tenant administration portal from the beginning.

I am the only administrator, and Microsoft 365 Admin Center also returns HTTP 401 Unauthorized.

Could you please advise whether I should create a Microsoft 365 Business Basic trial solely to raise a support ticket, or whether there is another official way to recover my existing tenant without creating another subscription?

Thank you for your help.

Dear @Zeel Patel

Thank you for confirming. I understand your concern about creating another subscription when your goal is simply to recover access to the existing tenant.

Since you are the only administrator, have never been able to access the Microsoft Entra Admin Center, and cannot open a support request through the affected tenant, you can create a temporary Microsoft 365 Business trial tenant and use it to contact Microsoft 365 Business Support.

Please do not worry about keeping the temporary tenant permanently. Once Microsoft Support has successfully created/taken ownership of your recovery case and you no longer need the temporary subscription, you can cancel the trial before it converts to a paid subscription. I recommend checking the trial's renewal/cancellation date and keeping the temporary tenant accessible until your support case is resolved.

Microsoft's guidance for contacting business support is available here: Get support for Microsoft 365 for business

I understand this adds an extra step, but it can provide a practical route to reach Microsoft Business Support when the affected tenant itself cannot be used to create a service request.
