Flow app asks for Mail.ReadWrite, Files.ReadWrite.All for one mailbox action

Default scopes are often too broad. Ask for minimal scope or use a fine-grained app.

Try this first

  1. 1Read app scopes before consenting
  2. 2Where possible, scope down via tenant admin to specific mailboxes or sites
  3. 3Use service principal with fine-grained role assignment
  4. 4Review connected apps every quarter

When to bring us in

Broad scope not narrowable: pick another connector or build custom.
