I have about 8 years worth of email on my local PC in Thunderbird, but I'm getting into a position where it would be better for me to drop the local program and just use Webmail. It has all of the features that I need, I have a ton of excess storage on the server, a better server backup, and I won't have the lag time that I get with Thunderbird.

So, the question is... is it possible to export my emails from Thunderbird, and send them back to Webmail?

Easiest way I can think of is to add your remote mailbox as an IMAP mailbox into Thunderbird. Make sure you remove any POP3 settings that will redownload the mail at the same time.

This will allow you to drag/drop everything back onto the server. Once done you can use both Thunderbird and webmail to access the IMAP folders without removing them from the server.

The only thing to note is that Thunderbird sometimes does its moving in the background and it will appear like it is not doing anything. If you want to check on the progress, use webmail to see if things are starting to appear and leave Thunderbird to do its business. Give it too much to do in one go and it might trip over itself.
