Resolved Email client can't store send mails in folder Send

[andreios]

My email client Thunderbird can't store mails in the specific folders like Send or Drafts.
Also I can't change subscription options of my IMAP accounts. It shows just nothing.

The "IMAP server directory" in the extended mailbox settings must be set to: INBOX

Where do I find the extended mailbox settings?

Ok interesting, for what ever reason it works now.
