Registering an application return quota limit error.
I have a brand new Microsoft 365 Business Premium tenant with approximately 490 users and 137 service principals. I am a Global Admin with a Business Premium license assigned. I have verified a custom domain. The "Users can register applications" setting is enabled.
When attempting to register an application I receive: "The directory object quota limit for the Principal has been exceeded."
I ran the following PowerShell to check the tenant quota:
Connect-MgGraph -Scopes "Organization.Read.All" $org = Get-MgOrganization $org.AdditionalProperties["directorySizeQuota"]
The total value returned is 500.
This appears to be a provisioning issue where the tenant's directorySizeQuota has not been updated to the standard 300,000 object limit despite having a verified domain and Business Premium licensing.
M365 support directed me to Azure support, and Azure support only allows billing tickets without a paid support plan. Paid support plan options do not populate and the portal goes non-responsive. Hoping someone here can advise or escalate.

Your tenant has reached the default directory object quota limit of 500, which accounts for the error encountered when attempting to register new applications. Under a Microsoft 365 Business Premium subscription, the expected quota is typically significantly higher, 300,000 objects. This discrepancy indicates a provisioning anomaly that requires escalation through Microsoft support channels for resolution.
