Q: Cannot Delete Apple Mail Mailboxes on "On My Mac": What Should I do?
I have tried deleting these mailboxes multiple times in multiple ways, but, no matter what I do, they just keep reappearing.
I have 1) right-clicked and deleted them multiple times; 2) I have deleted them through Finder; 3) I disabled my email accounts and tried to delete the mailboxes (which some have had success with apparently); 4) I changed mailbox behavior by un-clicking and then re-clicking the put deleted emails into trash box (which some suggested online).
I have no idea what to do next. I am speaking with Apple, but I thought I would try here to find a solution to this aggravating problem.
Thank you.
iMac (27-inch, Late 2013), Mac OS 10.11.16

OK I figured this out.
When I imported messages from Thunderbird to Apple Mail, I initially converted them to mbox files. Then I imported them in Apple Mail via the Apple Mail Import feature. I made the mistake of including mbox files that were linked to IMAP accounts. After hours of trying to delete, I tried the suggestion above. I deleted every internet account including iCloud. Then I deleted the imported mailboxes that were linked to IMAP accounts. That worked, and the self-recreating mail boxes are now gone.
