Hi, I am using Thunderbird 38.30 as my main email client. I created a folder and tried to delete it but it keeps coming back multiple times. I keep deleting it to no avail.

How can I stop this?

Chosen solution

First follow this process.

  • Right click on sub-folder and select 'Delete'

It should get moved into the 'Deleted' or 'Trash' folder.

  • Right click on the 'Deleted' / 'Trash' folder
  • select 'Empty Deleted/Trash'.
  • Close and restart Thunderbird.

Did it come back?

If yes: Make hidden files and folders visible.

In Thunderbird

  • Help > Troubleshooting Information
  • click on 'show folder' button

a new window opens showing the contents of your profile folder name.

  • Close Thunderbird now - this is important.
  • Scroll down and delete this file: foldertree.json

(a new one wil be created when you restart Thunderbird later).

  • click on 'Mail' folder
  • click on pop mail account name

Sub-folders are kept in folders with a .sbd extension. Example: if the problem sub-folder is a subfolder of the Inbox; click on 'Inbox.sbd' folder

So you would need to apply the same logic to locate the problem sub-folder. The sub-folder you want to delete will not appear as a 'Folder', but it will have the same name as your sub-folder. It will be an mbox 'File' (which has no extension). There will also be an index file with a .msf extension.

  • delete both the mbox file and the .msf file of same name.

So if your Folder Pane structure was something like this: mail account name > Inbox > > Bills > > > > Gas

> Friends > > Bob > > Anne

example to locate 'Gas' In the profile mail account name click on 'Inbox.sbd' click on 'Bills.sbd' locate and delete : 'Gas' File - no extension 'Gas.msf' file

example to locate 'Anne' In the profile mail account name click on 'Friends.sbd' folder locate and delete : 'Anne' File - no extension 'Anne.msf' file

After deleteing the files as specified.

  • Close window - top right X
  • Start Thunderbird.

I'm presuming you use an imap mail account. Thunderbird would be subscribed to see that folder.

Q: Can you unsubscribe from seeing that sub-folder ? Q: Logon to webmail account using a browser - is that sub-folder still on server ?

Hi Toad-Hall,

I am not using IMAP mail account, I have POP The folder is not on my web mail account.
