Priority Cleanup V2: Faster, Simpler Data Purging for Exchange Online

There is no way to scope administrative authority. Any user assigned the Priority Cleanup role can create policies targeting any mailbox in the tenant, regardless of business unit or ownership model.

In large, federated organizations, this prevents safe delegation to BU or regional admins and forces Priority Cleanup to operate as a fully centralized service, reducing responsiveness for legitimate local incidents.

Requested enhancement: support admin‑level scoping (for example, by adaptive scope, mailbox set, or Entra Administrative Unit), separate from policy targeting, similar in concept to Exchange RBAC or Administrative Units—while retaining existing approval and audit controls.
