Cannot delete IMAP Folder

I've read many threads on this, none of which seems to work. Most grateful for assistance to finally get rid of these phantom folders.

Problem: Multiple folders in an IMAP account that simply will not delete.

Symptom: Folder exists in an IMAP account that has all folders as sub-folders under Inbox. Some folders are empty and appear greyed out and italicized. Deleting them sends them to the Deleted folder (or if the appropriate setting is changed, to be immediately deleted). Emptying the Deleted folder appears to get rid of the deleted folders, but restart and they reappear.

Attempted Fixes: As suggested in various places, have tried these things, none of which work:

  • Immediate delete (setting and also simply deleting in the Deleted folder)
  • Creating a new folder of a different name and renaming it to the affected folder, then deleting -- would not rename new folder, and phantom folder remained
  • Completely removing the account (settings and data) and recreating

Other Actions: I have checked the actual IMAP account via a webmail interface and none of the folders exist in the account.

Thanks. I had actually tried that, but it seems I needed to restart to see its effect.

Those many folders still exist if I look at the Folder List for Subscribe. Given that they do not exist in the original email account, how do I get rid of them in Thunderbird completely?

Thanks.

The folder list in Subscribe is generated by the server, so I think the best you can do in TB is to hide them by the method you used.
