Hi @Eriko • Thank you for reaching out.
There is a limit defined for directory objects in a given Azure AD tenant, which includes users, groups, applications, and servicePrincipals. By default, a maximum of 50,000 Azure AD resources can be created in the Free Edition of the Azure Active Directory tenant.
When you add at least one verified domain in the tenant, the default Azure AD directory object limit is raised to 300,000. To go beyond the default quota, you must contact Microsoft Support and for the free edition of Azure Active Directory tenant, you can get it raised up to 500,000. If you have Azure AD Premium P1/P2, you can get it raised beyond 500,000 by contacting support and providing a business justification for the same.
