Until now, I've accessed my work email through the online client (it uses a POP server). But earlier today, I added the account to Outlook so that I could see my older emails offline as well.

But after I did this, every single one of my past emails (going back years) was deleted from the online client though I can see all of them on Outlook. This is disastrous, since I need to access my work email from public computers as well.

Please help me import my old emails back to the web client! If it helps, the web client is Zimbra.

Thanks very much for your help,
Rachel
