Microsoft 365 mail verified; approve whole domains
Emails from Microsoft 365 senders are now checked correctly, so fewer of them need manual approval. The Security page updates for new mail only, so older verdicts stay the same.
Each approved sender address now has an "Add *@domain" button. Clicking it approves the whole domain, merges your existing entries into it, and keeps their shipment counts. Consumer mail domains do not get this button.
