Hi, I have asked this question before (maybe about a year and a half ago or so), but there was no solution found, and it seemed like nobody else was having the same issue. As it keeps re-occurring, I made a new thread: Thunderbird creates duplicates of other inbox folders on 'Local Folders'. This seems to happen at random and just by itself. Then I delete the folder, but a few days/weeks/months later there is another duplicated inbox folder on Local Folders. It's very strange, it is some inbox on one of my e-mail accounts and it's being duplicated as inbox in 'Local Folders'. I don't know if this has anything to do with it, but just as extra info: a while ago when I re-installed my OS (Win 7) I copied the Thunderbird profile folder in order to keep all my folders, e-mails and settings. Another info: all my e-mail-accounts are POP accounts. Anybody else ever encounter the same problem? I hope someone can help me solve this issue, any help is much appreciated! thanks, Lars
