Uploading emails form other offline email client

[santoshj]

Hi,

I am user of Zimbra mail from our organization. I am working on Linux platform and have Thunderbird 3.0b2 email client.

Recently I migrate my Zimbra mail account with Thunderbird 3.0b2; after finishing migration Thunderbird 3.0b2 downloads all mails from Inbox to desktop and that mail's are removes form Inbox of my Zimbra mail account (which may default operation & I am not aware of this operation).

Is there any way to revert back this operation or recover that mail back to Inbox, because if I want to refer my old mails over the internet I can't do. Currently I have all of my mails in Thunderbird client.

Please help me out form this problem.

Thanks & Regards,
Santosh
