I want to get in admin setting

Sign in with the school IT account at portal.office.com, open the app launcher, and select Admin; if Admin is missing or access is denied, the account does not currently have the required administrator role.^1^

If your school already has an administrator

An existing administrator must grant your account an appropriate role:

1. Ask the current administrator to open the Microsoft 365 admin center.
2. Go to Users → Active users.
3. Select your school IT account.
4. Select Manage roles.
5. Choose the role needed for your work and select Save changes.^2^
6. Sign out, sign back in, and open Admin from the app launcher.

Use the least-privileged role that covers your tasks—for example, a limited administrator role rather than Global Administrator. Global Administrator has access to almost all organizational settings and data.^3^

Calling the account a “school IT/admin account” does not itself grant administrator permissions; a role must be assigned to it.

If “Become the admin” appears

This path applies only when the school account belongs to an unmanaged tenant created through self-service signup and no administrator has yet been established:

1. Sign in using the school-provided email address.
2. Open the app launcher and select Admin.
3. On the Become the admin page, select Yes, I want to be the admin.
4. Select Verify.
5. Add the requested DNS record to prove that the school owns or manages its email domain.
6. After verification, return to Microsoft 365 and open Admin.^4^

This requires access to the school domain’s DNS configuration. If Become the admin does not appear, an administrator is already in place, so this takeover procedure does not apply.

If this is a managed tenant but no administrator can sign in

Do not use domain takeover for a managed school tenant. If you are the only Global Administrator—or no existing administrator can access the tenant—contact Microsoft’s Data Protection team for administrator-access recovery:

1. Open Microsoft’s customer-service phone-number page and call the number for your region.
2. Give the reason as AdminCenter.
3. Identify the affected role as Global Administrator.
4. When asked whether another administrator exists, answer No only if that is true.
5. Request creation of a service request for the Data Protection team to recover admin access.^5^

Be prepared to verify that you are authorized to act for the school.
