Lumia phones seem to be a nightmare:

"Talking about preferences, is it possible to install an individual ring-tone? If yes, how, it is not obvious. At least it is quite simple to change the colour of the icons. When I set-up the email I could not find if the POP-mails will be left on server or deleted, there is no setting about it, so I assume (hope) they will be left on server."
