I have a client who uses the Thunderbird email client. It appears that one of the mailboxes/email addresses is corrupt. When he tries to read email in that mailbox Thunderbird crashes. However, this doesn't happen with any of the other mailboxes/addresses.
I think I'm going to delete the mailbox/address and re-add it but wanted to make sure the email currently there won't disappear. And, is there a way to re-sync the old emails to the newly setup address.
From my reading about it it seems that that is possible since there are separate files for each mailbox/address.
