The Outbox contains messages that have been queued for delivery. A maximum of twenty faxes are queued at any given time (each phone number in a fax with multiple recipients is counted as a separate fax in the queue). The speed with which the queue clears will depend on the complexity of the images being faxed and the length (number of pages) of each fax.
Fax-to-Email will make 5 attempts to send your fax to each recipient. Once a fax has been successfully sent, the fax will be automatically moved from the Outbox to your Archive folder; you will also receive a notification by email that the fax was sent successfully.
When a fax is queued in the Outbox it can be removed using the "Delete" icon located in the right-hand column.
