How to save all sent messages to Local Folders?

Can someone tell me how to save messages sent from either of my accounts to the Sent folder of Local Folders? Thanks

You would need to create a Rule for this.

Go to Menu > Rules and create a new Rule:

Thanks Gary. That worked, but now the sent message is in 2 places ie, the sent folder of account and the sent folder of Local Folders. The term move suggests it would be removed from the Sent folder of account. Not true?

Update: just discovered the option to subsequently delete message. That works although I’m still confused by the use of the word ‘move’

The Rule will move the message to your selected folder, but at the same time the server may be creating a copy of message in its Sent folder as well. Does not happen with all servers though.
