Hi I have 2 email accounts that have V2 folders and if I delete them they come back. I have no idea what they are and why they are there. I thought it might be from my host but they are not on the host only in Thunderbird. I also have in every email account today 2 spam folders and a junk folder. I can't delete the extra spam folder and shouldn't there be either a spam or junk folder not both?

Each email account has a lot of folders in there now and I am wanting to simplify them please. For example one account contains these folders: inbox spam drafts sent archive junk trash spam V2
