Hello! I want to make a new totally clean installation of TB to get rid of the grey/italic folders issue (the folders and it's structure is correct on the IMAP server and as well display in K9 Mail on my mobile and none of the solutions posted here, such as renaming the folders etc. did work). What I did so far: - Uninstalled TB - Deleted the profiles folder in the user folder (both in "local" and "roaming") - Deleted remaining TB folders in "ProgramData" and "Program Files (x86)" - Emptied trash bin - Restarted But... After installation the old folder incl. the grey/italic folders appear again. Does TB store under different names the previous profiles? How do I force TB to load totally new the folder structure as it is on the server? Any hints are mostly welcome! Best, Wolfram
