Take control of Fabric Identities limit for your tenant (Generally Available)
Fabric Identity governance at scale just got easier. We are introducing a new tenant admin setting that gives you control over the maximum number of Fabric identities (hence Workspace identities) in your organization.
With this update, Fabric tenant admins can:
- Scale beyond previous constraint — the default limit for number of Fabric identities in an organization increases from 1,000 to 10,000 identities.
- Set custom limits for how many Fabric identities can be created in their tenant.
- Manage limits programmatically by using the Update Tenant Setting REST API.
How it works
The new setting “Define maximum number of Fabric identities in a tenant” is located in the Fabric Admin portal in Tenant settings, within Developer settings.
When the setting is disabled (the default), your tenant supports up to 10,000 Fabric identities — a 10x increase from the previous limit. Enable the setting to specify your own maximum. The value you enter becomes the upper limit for Fabric identity creation across your tenant.
Note: Fabric doesn’t validate that your custom limit falls within your Entra ID resource quota. Before setting a custom limit, check your organization’s Entra ID service limits.
If a workspace admin tries to create a new workspace identity that would exceed the limit, they’ll see a clear error message explaining the reason.
You can also manage this setting programmatically using the Update Tenant Setting API.
