The steps you need to follow to leave POP3 email on the server depends on your version of Outlook.
The dialog is identical in all versions of Outlook. If your dialog does not look like the one at the right, verify your account is a POP3 email account.
In Outlook 2010 (and Outlook 2013), the default is to leave all mail on the server for 14 days. This change was made to prevent problems when people set up new accounts and wanted mail left on the server but opened Outlook before setting Outlook to leave mail on the server. Once it's downloaded by POP3, it usually can't be put back. See Restore POP3 Mail to Server for methods.
Only POP3 email can be left on the server or deleted. IMAP, Hotmail Connector, Exchange server, and EAS account types are server-based accounts and mail is always left on the server. If you want to delete the mail from the server with these account types you need to use rules to move your email to a local pst file.
