IMAP synchronization problem

I’m having an issue with IMAP folders. I have tried to create a new folder via webmail and the eM Client downloaded it. After i created a folder on the eM Client but this folder is not beeing syncronized with the server. Is there something i need to do for it to work?

Hi, can you tell me what eM Client’s version exactly do you use? Also who is your email service provider?
