Recently reinstalled Windows 10 on my system and then reinstalled Thunderbird for my email.
I see a grayed out folder named 'New%20Folder-0' which is not one I created. If I try to delete it (from Thunderbird), I get a message that the command did not succeed and that the folder does not exist.
If I look at the BT EMAIL account via my wen nrowser, sure enough there is no such folder shown.
I suppose this means that it is a Thunderbird issue. I found a reference to 'New%20Folder-0.msf' in the Mail folders of Thunderbird, but deleting was no good as Thunderbird just re-created it.
Can any one shed light on this?
