erase original email

I’ve been using eM Client for months and love it. As added one more email account a few days ago, I wonder if there is any option if I can choose either erasing original emails or leaving them. I’ve gone through with such keywords but not been successful. Please help. 

Are you asking about deleting the old emails from the server?

eM Client will always download whatever is on the server the first time it connects to an account. There is no way to choose not to do that. If you are using POP3, you will only get the Inbox and all other folders will be ignored. IMAP and Exchange will sync everything.

Yes, you’re right.
