IMAP (Internet Message Access Protocol) is a standard email protocol used to access emails of a web server to local system. This will help users to get a copy of cloud emails to local system.
In other words, users can read IMAP server emails on desktop, laptop computer, etc. This protocol helps users to work on multiple computers in multiple locations.
IMAP protocol generally works on two ports –
Port 143: Default IMAP non-encrypted port
Port 993: Port to use if you connect using IMAP securely
To backup cloud emails, you need to have correct IMAP settings. You need to provide host name, port name, IMAP account username, and password.
