How to Fix the Microsoft Entra ID 500-Object Directory Quota Error
Product
Microsoft Entra ID
Device & OS
not provided
Scenario
Creating new users, groups, or applications within a Microsoft Entra tenant.
Observed behavior
The system blocks the creation of new objects and produces error AADSTS90093 due to an incorrect 500-object directory quota, ignoring the standard 50,000 or 300,000 object limits.
Before you start

Ensure you have global administrator access to your Microsoft Entra ID admin center and have your Tenant ID ready before reaching out to support.

Solution 1Recommended

Contact Microsoft Support to Correct Tenant Provisioning

Since a 500-object limit is a backend configuration error, reaching out to Microsoft Support is the only way to restore the standard default directory limits.

By default, Microsoft Entra ID allows up to 50,000 objects for tenants without a verified custom domain, and up to 300,000 objects for tenants with a verified custom domain. A 500-object quota is an unexpected provisioning failure that requires backend intervention by Microsoft engineers.

1
Gather your tenant information

Log in to the Microsoft Entra admin center and locate your Tenant ID from the Overview page.

2
Document the exact error

Take note of the exact error code (AADSTS90093) and collect the directorySizeQuota values reported through Microsoft Graph.

3
Open a support request

Navigate to 'Help + support' in the admin center and create a new support request. Provide your Tenant ID and the collected error details privately to the support agent.
