Here's the situation; on my mom's MacBook Pro, all the Drafts and Sent Mail folders are suddenly empty. She can save new things in them, but everything else is gone. Apparently she saved lots of notes in drafts and everything is missing. Additionally, one of her POP inboxes is delivering messages twice and always showing them new, even after she views them. The duplicates have the same title but the bodies say: "The message from no-reply@*****.com concerning “******” has not been downloaded from the server. You need to take this account online in order to download it." Her signatures are missing as well. There is one .Mac account and three POP accounts; no IMAP accounts, unless that's what .Mac uses. Has anyone encountered this before, or has any troubleshooting ideas? Thanks.
