How can i tell if I am using POP or IMAP email protocol in Outlook?

You are reading this article as we have asked you to tell us if you are using IMAP or POP in your email settings in Outlook.

What is POP?
Generally POP stores your mail on your own PC as a .pst file. POP supports simple download-and-delete requirements for access to remote mailboxes. Although most POP clients have an option to leave mail on server after download, e-mail clients using POP generally connect, retrieve all messages, store them on the user's PC as new messages, delete them from the server, and then disconnect. 

What is IMAP?
IMAP allows you to store your mail on the server allowing access via many devices. The Internet Message Access Protocol (commonly known as IMAP) is an Application Layer Internet protocol that allows an e-mail client to access e-mail on a remote mail server. An IMAP server typically listens on well-known port 143. IMAP over SSL (IMAPS) is assigned well-known port number 993.

How can I tell which protocol i'm using?

1. Go to FILE/INFO/ACCOUNT SETTINGS and select Account Settings.
2. Open an email account and check the ACCOUNT TYPE under SERVER INFORMATION.
3. It will say either POP or IMAP (see image below)
