Managing external identities to enable secure access for partners, customers, and other non-employees
The documented limit for Microsoft Entra External ID external tenants is 300,000 total objects (user accounts and applications) per tenant. The documentation states that to increase this limit, Microsoft Support must be contacted, but it does not specify a published maximum upper bound beyond 300,000.
For scenarios that require more than 300,000 objects, the supported path is to:
- Operate at the default 300,000-object limit.
- Submit a support request to increase the object limit for the tenant.
Any higher limit and its ceiling (if any) are determined on a per-tenant basis through Microsoft Support and are not documented as a fixed, global maximum.
