If you want the old mail on the zimbra server, you have to use the import wizard.
If you do not care whether the mail gets uploaded to Zimbra and the old PSTs are from a non-MAPI account (pop, imap, or hotmail), then try this (untested):
Create a fresh zimbra profile;
Add a new POP/IMAP account within the Zimbra profile, with incoming server 127.0.0.1 and a valid outbound SMTP;
Configure Send/Receive to never poll the dummy account;
Quit Outlook;
Overwrite the blank POP PST with your old one. |
