How can I keep sent messages from appearing twice in the ” sent ” folder. I am using outlook.com and hotmail.com e-mail addresses with IMAP.
Each time I send a message with Thunderbird the sent message is put in the “sent” folder two times.
What setting needs to be changed to in order to have only one copy of the message put in the “sent” folder?
Outlook/Hotmail and gmail automatically put copies of sent mail in the imap sent folder. If you have settings to also keep a copy then two are being put in the sent folder.
right click on imap mail account in Folder Pane select 'Settings' select 'Copies & Folders' in 'When sending messages, automatically:' uncheck : 'Place a copy in:' click OK

Have a nice day!
