You plan to provide external users access to several host pools. Which host pools will be billed using per-user access pricing?

Per-user access pricing for Azure Virtual Desktop applies to external users accessing host pools that are not covered by an eligible Windows or Microsoft 365 license. Pool1 and Pool2 are designated for external users, meaning they will incur per-user access charges. Pool3 is for internal users, who are assumed to have eligible licenses, so per-user access pricing does not apply. Pool4 is for internal users with eligible licenses, further exempting it from per-user access charges. Therefore, only host pools serving external users without eligible licenses are subject to this pricing model.
