Thunderbird: restore lost folders


It looks like Thunderbird silently deleted some important folders (I wondered why some messages remained in the inbox). It looks like the directories and mails still are there, e.g. in Data\profile\Mail\local\<containing-folder>.sbd\<folder>.

How can I restore the folder in Thunderbird?

Best Answer

It looks like there is not just the <containing-folder>.sbd directory, but also a <containing-folder> file. After having restored that from a backup, I could access the subfolders again. If the <containing-folder> did not contain important information, but the subfolders do, one also can reactivate the subfolders by creating an empty <containing-folder> file.
