I want to change the settings for mail list columns (order, width, …) over all subfolders in a account. How can I do this? If I change the settings in Inbox the subfolders keep the default settings 
Many thanks.
Right-click on a column header and choose Apply Column Configuration . . .
ok, the german translation is some confusing, like “apply column order”.
but it has worked 
What version of eM Client are you using? You can always check if you are using the latest at the Release History.
If you are using an older version, it may already have been changed. If not, if you give a better (correct) translation, I will pass it on to the developers for correction in the next version.
