Detailed explanation-1: -You can be logged in with multiple computers and devices simultaneously. Your mail archive is synced and stored on the server for all connected devices to access. Sent and received mail is stored on the server until the user permanently deletes it.
Detailed explanation-2: -POP3 only allows a single device at a time to access the emails. IMAP allows multiple devices at a time to access and read the available mails. A user cannot update or create emails on the mail server by using the POP3 protocol. You can use the IMAP protocol for updating or creating emails.
Detailed explanation-3: -IMAP stores email on your provider’s servers. It provides you reliable off-site storage of your emails. If your email data is important to you, IMAP is the better way to go. If you’re dealing with email on multiple devices-say a mobile device and a desktop computer-IMAP automatically keeps everything in sync.
