One of my mail accounts set up in Thunderbird is a Plusnet account. I moved a subfolder to the top level of that account in the folders view, but instead of appearing in the same list of all the other folders in that account it appeared as a subfolder of that account in the Inbox list of accounts. Having tried everything I decided to delete the whole account from Thunderbird and recreate. That only made things worse - now '''''all''''' of the folders in the newly re-added account appear under it in the Inbox part of the tree. In the picture which I've obfuscated slightly by changing all the account names to generic names. "My mail account 1/2/3" are existing accounts. Note that for My mail account 1 the folders of that account appear under that specific account. For newly (re-)added account, which used to behave in the same way until (a) I tried moving one its subfolders and (b) removed it from Thunderbird and re-added it, the folders appear as a subfolder of it under Inbox. How do I get these folders to appear in the correct place and not under Inbox? This is not a Plusnet feature, one of my other accounts is also with Plusnet and that behaves correctly.
