First things first: keep in mind that the security encryption version used by your email client is dependent on the operating system of your device as well as the performance of your client application. Cox suggests that you update the operating system on your device and your email client to the most recent versions made available by the manufacturer. This process upkeep will ensure that you are utilizing TLS 1.0 or a higher version.

💡 Note: Before continuing with the instructions below to change your mail clients from using POP server settings to IMAP server settings, Cox highly recommends that you make a backup of any critical emails you wish to keep before continuing.

IMAP or POP3: What Is The Difference?

Post Office Protocol 3 (POP3) is a method for downloading emails from a server to a single computer, after which the emails get removed from the server where you stored them. On the other hand, the Internet Message Access Protocol (IMAP) saves the message to a server while synchronizing it across various devices.

Choosing between POP3 and IMAP is a matter of personal preference.

When it comes to getting emails on several devices, IMAP is the preferable method. If you would rather be able to view your emails even when you are not connected to the internet and already have a specific device for managing your email, then POP might be a better choice for you.

Generally, IMAP is preferred over POP3 by the vast majority of users due to the former program's greater adaptability.
