Simple way (it's work!):
- You must have enabled IMAP server in Zimbra (informations only for Zimbra admins)!
1. Add in your desktop Client (Thunderbird / Outlook) zimbra IMAP server (new IMAP user account - eg. my account IMAP1 - use IMAP / IMAP4, not POP3 protocol).
2. Move in Thunderbird or Outlook your messages - drag and drop - from your local desktop client folder (like local Sent mail) to Zimbra account IMAP structure.
3. (OPTIONAL STEP) Modify your folder structure for best visualisation from Zimbra web client or Zimbra Desktop Client
Done.
