Cannot Delete Mailboxes in

by David   Last Updated September 11, 2019 23:12 PM

macOS 10.14.6, v. 12.4 (3445.104.11), 2015 iMac. The software is up-to-date.

I was looking for a possibly-deleted email, and searched several Time Machine backups. I found one possibility, and restored it. It turned out not to be what I sought, so I deleted it.

Now, however, I'm left with extra mailboxes in

enter image description here

You can see them here as " Backup" and "Recovered Messages." "Recovered messages" is empty, and I cannot delete either mailbox. Similar mailboxes in the past (when I've used TM to recover emails) were easily deleted.

I have rebuilt them both (Mail > Mailbox > Rebuild), which only makes the single I email I thought might be my target reappear in the "Recovered Messages" email folder.

I've also restarted the computer, both normally and into safe mode. These had no effect either.

I used the Mac's Finder search, and found three files named " - note the difference that the word "mail" is not capitalized, as it is in these mysterious mailboxes. These files are all located on a mounted bootable backup disk which is created nightly using ChronoSynch. The file path displayed in the Finder window says these files are located at the root level of the bootable disk in a folder named "private." Opening the bootable disk reveals no folder named "private."

I'm mystified. Can anyone explain what's going on here? How can I get rid of these folders?
