Office 365 Admins – Turn off Tenant Creation Now
Office 365
(Azure AD)

A new setting has appeared in Azure AD User settings which controls if member users can create their own new Tenants. By default this setting is enabled for all users.

This will allow them to create their own tenant and set them as a global admin of that tenant.
To disable:
- Go to user settings blade: https://aad.portal.azure.com/#view/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/~/UserSettings
- Change “Tenant creation” setting to No
- Save settings
When restricted only Global Admins or users with tenant creator role can create new tenants.
