Check progress and history
Progress shows sent messages, failures and total recipients. At a delivery limit, a waiting message displays when sending will resume automatically.
Delivery history shows the subject, time, requesting administrator, sender, audience and delivery counts, including messages not sent. Check the sender's connection and authentication when failures occur.

Stopfor the running delivery. - Confirm in the dialog.
- Check the result and sent count.
The message currently being sent may still be delivered. Previously sent messages are not recalled, and remaining recipients do not receive mail.
Handle automatically stopped or interrupted delivery
Repeated sender-side failures automatically stop delivery. Restarting the server can interrupt a delivery.

- Check the reported cause and remaining recipients.
- Resolve mail service or external authentication problems.

Resumeand confirm. Recipients who already received mail are not sent another copy. - To end the delivery, select
End mailingand confirm. Remaining recipients are skipped and the result is saved in history.
Delivery cannot resume after the sender mailbox changes. Restore the original sender or close the delivery. Starting a new delivery while one is paused warns that the remaining recipients of the old delivery will not receive it.
If another administrator changes the delivery state while you confirm, the action is rejected with an explanation. Check the current state and try again.
