I have changed web hosting provider and now have new IMAP/SMTP server details (same e-mail address "user@domain.com"). I have created a new e-mail account in Thunderbird Beta with the new details and this works fine. However, the existing e-mail account for "user@domain.com" which is using the old IMAP/SMTP details has thousands of e-mails previously downloaded. Some of these e-mails are still readable in Thunderbird Beta but the majority now say "Go Online to View This Message" in the preview pane. I no longer have access the the old web host. If I look in the profile directory for this account, it looks like the e-mail is there. Is there a way of copying these e-mails to the new e-mail account? Many thanks
