No mails in any folders except inbox

I have just downloaded em to try out, I see all the the imap folders and sub folders that I normally have in my other e mail program but there are no mails in them, I keep getting a message that my account is off line but I’m getting email in my inbox so this cant be true, I have tried ticking work offline but this does not change anything, so what am I missing

Hi, what email service provider do you use and what version of eM Client exactly do you have?
