How to Select Where Sent Messages Are Kept in Mozilla

Make a new Sent file in Thunderbird

Mozilla Thunderbird automatically keeps a copy of every message you send. By default, it places that copy in the Sent folder of the account from which it is sent. But you can change this to be any folder in any account. For example, you could collect all sent mail from all accounts in the Sent folder of Local Folders.

Instructions in this article apply to Mozilla Thunderbird 68 or higher on Windows 10, 8, or 7; Mac OS X 10.9 or higher; and GNU/Linux.
