HELP LOCATING ORGANIZATIONS USER ADMINISTRATION ACCOUNT

Microsoft cannot disclose the administrator’s contact information; first identify the person who purchased or established the Microsoft 365 subscription, and if no administrator is available, initiate tenant-access recovery through Microsoft 365 Support.

1. Identify the existing administrator

The person who originally signed up for and purchased Microsoft 365 for business is normally assigned Global Administrator automatically.^1^

Check with:

• The business owner, executive director, or employee who purchased Microsoft 365.
• Current and former IT staff or consultants.
• The person who provided employees with their Microsoft 365 usernames and passwords.
• The Microsoft partner or reseller that created or manages the tenant.

Microsoft does not maintain administrator contact details that it can provide to ordinary users, so administrator discovery normally starts within the organization.^2^

2. If someone can access the Microsoft 365 admin center

Have that administrator sign in at https://admin.microsoft.com, then:

1. Select Roles → Role assignments.
2. Select the Microsoft Entra ID tab.
3. Open Global Administrator to see the currently assigned administrators.
4. Select Add users and add the trusted replacement administrator.
5. Alternatively, go to Users → Active users, select the new administrator, and choose Manage roles.
6. Assign the appropriate role and select Save changes.^1^

Verify that the new administrator can sign in and access the required SharePoint and migration settings before removing or disabling the former administrator.

Global Administrator has extensive access to organizational settings and data. Assign the least-privileged role that meets the operational need, and retain a separate recovery administrator so one unavailable account does not lock out the organization.^3^

3. If no administrator can be found or accessed

Tenant access must be recovered through Microsoft’s identity-verification process:

1. Go to the Microsoft 365 support page.
2. Select I can’t sign in or access my tenant.
3. Request recovery of administrative access and explain that the organization cannot identify or reach its Global Administrator.
4. Be prepared to provide:
   • The organization’s legal name and Microsoft 365 domain.
   • The original registration or purchasing email, if known.
   • Official organizational documentation.
   • Evidence that the organization controls its internet domain.
   • Public registration information, where applicable.

Microsoft Support handles tenant ownership and access decisions; access cannot be granted without verification.^4^

If a Microsoft partner purchased all subscriptions for the organization, contact that partner first. Microsoft’s direct online business-support route requires at least one subscription purchased through Microsoft; partner-purchased subscriptions are supported by the partner.^5^

Avoid creating a replacement tenant unless the organization intentionally plans a full migration. A second tenant can complicate domain ownership, licensing, and access to the existing SharePoint data.^4^
