HVE for Microsoft 365: When to Use It, When Not To, and Who Should Be Allowed to Send at Scale

Hi Lucaraheller, HVE is useful, but I would keep it tightly scoped. It is best for predictable internal high-volume mail such as application notifications, not for marketing, external campaigns, or anything that needs normal user mailbox behavior. Access should be limited to approved application identities or service accounts, with clear ownership, volume monitoring, and a review process. The biggest operational risk is letting it become a general-purpose bulk mail path without governance.
