Newbie question: I recently upgraded Ubuntu from 10.04 to 10.10 and during the process Evolution asked me to setup my accounts from scratch. I closed the window as I thought it was an error, I restarted the computer when the upgrade was finished, and as I opened Evolution again, I found all my account settings and contacts, but stored emails were gone, together with the folders they were in.

I created the folders again with the same name, and - magic! - the mails reappeared, but as I clicked on other folders and came back, they were gone again. Any ideas how to solve the problem?

I guess the messages are still there somewhere, but Evolution can't find them. I'd like to, or at least be able to import them on Thunderbird, instead of losing them all.

Thanks!
