I just installed a new Thunderbird 3 on a few computers and immediately saw that i could not find the "leave messages on server" option... can anyone point that out to me ? On my personal pc i upgraded Thunderbird 2 to 3 and there appears the option, but when i create a new account... i can not find the option, can anyone help me with this ...

Best regards, Mike.

This question came from our site for professional and enthusiast programmers.

Which protocol are you using: IMAP or POP? – Samuel K Dec 12 '09 at 9:29

Tools > Account Settings... > Server Settings

check the box Leave messages on server, now you can choose a number of days or until you delete them.

This option is only available for POP accounts. – Samuel K Dec 13 '09 at 7:01
This option is not available for IMAP, because the entire principle of IMAP is that your messages remain on the server. – Paul Lammertsma Jan 21 '10 at 10:53

I had the same problem. I found that I created an IMAP-account by mistake when i first created the account in Thunderbird.

To create a new POP account: Click the "Stop" button when Thunderbird tries to "help" you by automatically set things up. Then change "IMAP" to "POP".
