Hello @Eric Amzaleg,

Good day! Thank you for posting your valuable question on Microsoft Q&A forum.

The error "AADSTS5000224: We are sorry, this resource is not available" indicates that the resource you are trying to access is currently unavailable for your account.

This type of issue typically requires backend investigation. We recommend contacting the Microsoft Technical Support Team for assistance. Their specialists can run advanced diagnostics and, if necessary, escalate the case to the appropriate internal team for further analysis. This ensures the problem is formally tracked and resolved.

If your organization still has access to the Microsoft 365 Admin Center:

Find your Microsoft 365 admin: If you don't know who the global admin is in your organization, you can find guidance here: How can I find my Microsoft 365 admin? - Microsoft Support

Submit a service request: The Global Administrator should create a support request with Microsoft to receive advanced technical assistance. For detailed instructions, see: Get support - Microsoft 365 admin | Microsoft Learn

If your organization cannot access the Microsoft 365 Admin Center:

Please try to find the related hotline number to call the frontline and let them raise a ticket for you: Customer service phone numbers - Microsoft Support

Depending on your country or region. For some countries, when calling the support number, although there are about 30 seconds opening as something "you can visit the link...." But you can ignore this opening and wait until the option, then "1" as a business email user, "1" again for technical help.

If your organization's Office 365 Business/Education subscription is from a partner or reseller, and the global administrator is unable to open a service request on your end, contact the reseller's support provider to help open a service request on behalf of you instead.

I sincerely apologize for redirecting you to the Microsoft Technical Support Team. While we strive to assist as much as possible here in the forum, our resources are limited when it comes to backend-level diagnostics and advanced troubleshooting. Some issues require deeper technical analysis and access to internal tools that only the official support team can provide.

If you need further assistance, feel free to reply. I'm here and happy to help!

Answer 1

The error message AADSTS5000224 indicates that the resource you are trying to access is not available. This can happen for several reasons, including issues with account permissions, the resource being moved or deleted, or misconfigurations in your Azure Active Directory settings.

Here are some steps you can take to troubleshoot this issue:

Verify Account Permissions: Ensure that your account has the necessary permissions to access the resource. You may need to contact your administrator to check this.
Check Resource Availability: Confirm that the resource (in this case, your Microsoft Exchange Outlook account) is still available and has not been moved or deleted.
Contact Support: If the issue persists, it may be beneficial to contact Microsoft support for further assistance, providing them with the Request Id and Correlation Id from the error message for better tracking.

If you are an administrator, you might also want to check the Azure AD sign-in logs for more details on why the access was denied.
