Open the right mailbox
Open Mail and choose the personal or business mailbox you intend to use. Complete any device or mailbox setup requested before composing. Business access requires the relevant membership, licence and mailbox assignment.
Compose and send
Open the message composer. Enter recipients, a subject and your message. Review recipient addresses and attachments carefully.
Choose Send when it is available. If a recipient check or access warning appears, resolve it before sending. Save draft is separate from sending.
Inspect Outbox for recipient delivery status. A queued message or Sent copy does not, by itself, confirm that an external recipient has received the message.
When sending is uncertain
If the interface offers Check this send or a retry for the same attempt, use that recovery flow before starting a new send. Repeated new sends can create duplicate messages.
For custom-domain mail, ask the organisation owner to check hosting readiness and DNS. Never change DNS values based on an example screenshot.
