1
a place where unsent emails are stored
An outbox is the section of an email account where messages are stored temporarily before they are sent. It holds emails that are in the process of being sent or are waiting to be delivered. Once an email is successfully sent, it is typically moved from the outbox to the sent folder. If there is an issue with sending, such as a poor Internet connection, the email may remain in the outbox until it can be sent successfully.
