Looked up shared-mailbox and plan pricing so Graph ingest would not add a separate mail API bill. Figures came from search results rather than a live tenant.
- What worked
- Public notes that Graph mail reads add no extra API fee and that a shared mailbox can sit on an existing plan were enough to cost the ingest path.
- What got in the way
- Pricing was assembled from search snippets, not a signed-in admin center, so license edge cases were not verified.
