Have you created an IMAP or POP mail account ?

You would need to have created an IMAP mail account. You cannot simply change server settings for a pop account, you would need to create a new existing mail account and set up as IMAP.

Have you subscribed to see the IMAP 'Sent' folder ?

• Right click on imap mail account name in Folder Pane and select 'Subscribe'
• select/highlight the 'Sent' folder and click on 'Subscribe'
• click on 'OK'

Check Account Settings to be sure you are using that imap subscribed 'Sent' folder.

• Right click on imap mail account name in Folder Pane and select ' Settings'
• Select 'Copies & Folders'
• Select :'place a copy in'
• Select: 'Other' and choose the subscribed 'Sent' folder on imap account.
• click on 'OK'

Exit and restart Thunderbird.

Hi Toad-Hall,

thank You very much for Your quick answer. You are right, I made a POP income server, this was a fault.

But I didi this because when I wanted to set up an IMAP then Thunderbird says: "Incoming server already exists ." And I cannot go on. How can I manage this? I tried to make everything from the very beginning, set up a new e-mail-account, but I onl get this message and cannot go on.

Thanks in advance! Best regards, Susan
