directorySizeQuota not updated on new Business Premium tenant - cannot register apps
remium license assigned and a verified custom domain. The "Users can register applications" setting is enabled. The tenant has approximately 490 users and 137 service principals and no deleted objects.
When attempting to register any application I receive the error: "Failed to create BitTitan application. Error detail: The directory object quota limit for the Tenant has been exceeded. Please ask your administrator to increase the quota limit or delete objects to reduce the used quota. "
I believe the tenant's directorySizeQuota has not been updated to the 300,000 object limit expected for a verified-domain Business Premium tenant. I have confirmed this via PowerShell using Get-MgOrganization.
Microsoft 365 support (2603060010002144) directed me to Azure support. Azure support only allows billing tickets without a paid support plan. The paid support plan path gets me an unresponsive web page every time. I am unable to find any other route to get this resolved.
Can anyone advise, or help escalate to the Entra backend team to recalculate this tenant's quota?

If Get-MgOrganization is returning a directorySizeQuota total of 500 after you have a verified custom domain and paid Business Premium licensing, that sounds like the tenant is still being treated like the smaller/default directory quota tier.
A few checks I would do before escalation:
- Confirm the custom domain is verified in the same tenant where you are trying to register the app.
- Confirm the paid licenses are assigned in that same tenant, not in another tenant with a similar display name.
- Check deleted app registrations/service principals too, because deleted directory objects can still count until permanently removed.
- Try creating a very small test app registration directly in Entra admin center as Global Admin to rule out the third-party app flow.
- Capture the tenant ID, verified domain, license SKU, directorySizeQuota output, and exact app registration error.
If the total quota still shows 500, this likely needs Microsoft support to refresh/fix the tenant quota metadata. Community members generally cannot fix that from the tenant side if the quota value itself has not updated.

For a Business Premium tenant with a verified custom domain, the directory object quota should automatically increase to 300,000 objects. If the tenant remains capped at the default 50,000, this indicates that the quota recalculation has not been applied. Resolution of this issue requires intervention from Microsoft’s Entra (Azure Active Directory) backend team.
