## Definition

An **Outbox** is a collection of faxes that are in the process of being sent or have been sent recently. It serves as a management interface for outgoing faxes, allowing you to monitor their status and perform various actions.

## Key Concepts

### Fax Statuses in Outbox

Faxes in the outbox can have various statuses, including:

* **submitted**: The fax has been submitted to the system
* **converting**: The fax is being converted to the appropriate format for transmission
* **scheduled\_for\_sending**: The fax is scheduled to be sent at a future time
* **sending**: The fax is currently being transmitted

### Actions on Outbox Faxes

The Outbox interface allows you to perform several actions on faxes:

1. **Delete**: To cancel the fax transmission
2. **Download**: To retrieve a copy of the fax document
3. **Add note**: To attach a note to the fax for reference
4. **Resend/Forward**: To reuse the fax file for sending to new recipients

### Resending and Forwarding Faxes

You can reuse files from existing faxes without uploading them again. This is useful for:

* **Resending failed faxes**: Quickly retry a fax that didn't go through
* **Forwarding received faxes**: Send a received fax to new recipients
* **Bulk operations**: Send the same document to multiple recipients over time
* **Combining documents**: Append additional files to an existing fax. When combining, uploaded files are sent first, followed by the file from the existing fax.

When you resend or forward a fax, you can customize all parameters including destination numbers, cover pages, and sending options.

<Tip>
  To preserve the original quality when resending, set `options.enhancement: false` to prevent reprocessing the fax file.
</Tip>

### Monitoring Fax Progress

The Outbox is your primary tool for monitoring the progress of sent faxes. You can:

* See which faxes are currently being sent
* Track the success of your fax transmissions
