Account login error, error message: AADSTS500022

Hi, BabybooHN. Thank you for your answer.

The highest-level school administration I was able to contact informed me that they do not have the necessary authority, so I am unable to reach “the Global Administrator or Central IT Services of your school/university” as you mentioned.

I have very important personal project files in my OneDrive, and my account was suddenly disabled before I had a chance to back up anything. How can I find out who the tenant administrators are, or how can I contact the global administrator for my tenant to resolve this issue?

Dear @Bq

I completely understand how critical your project files are and how frustrating it is to be caught between a disabled account and local school administration.

Due to strict privacy, security, and compliance policies, Microsoft Support and community representatives cannot look up, disclose, or share contact details of Global Administrators to end-users.

However, you can use the following methods to identify where administrative control resides:

• Escalate Beyond Local School Admin: In many education systems, individual school site staff do not have administrative privileges. You need to contact the Central IT Department, District IT Office, or the University System Office that manages domain-wide services.
• WHOIS Domain Lookup: Go to a public lookup tool (such as WHOIS.com) and search your school’s domain (the domain after @ in your email address). Look for the Administrative or Technical Contact email/department listed on the domain registration.

Since your local administration does not have authority, they should escalate the issue to their domain/DNS administrator using these official options:

1. Perform an Internal Admin Takeover (If Unmanaged Tenant):
   • If your school’s tenant was created through individual self-service signups, an authorized IT staff member can claim administrative control by verifying domain ownership via a DNS TXT record.
   • Official Guide: Perform an internal admin takeover in Microsoft 365
2. Contact Microsoft Data Protection Support (If Tenant Account is Locked):
   • If an administrator account exists but is locked or lost, an official institutional representative must contact Microsoft Data Protection Support by phone. Microsoft can verify domain ownership with the school and restore admin access so they can re-enable your account and allow you to retrieve your files.
   • Support Directory: Microsoft Global Customer Service Phone Numbers

Because end-user files cannot be manually extracted by Microsoft without tenant-level authorization, I recommend passing the links above to your central IT department or domain owner so they can work directly with Microsoft Support to restore tenant access.

Please let me know if you need any further clarification.
