Learn more about IMAP server settings.


IMAP servers allow users to view email messages via an email client or application. IMAP offers features that POP does not, such as:

  • Support for simultaneous multiple access. New email is available and accessible from any client device at any time.
  • Partial fetch, only the sender and header information is downloaded, which leaves more storage on the device.
  • Two-way communication between client devices and the email server. This increases stability of the server.
  • Messages can be downloaded to the client device, if needed.
  • Actions to a message such as read or replied to, will be seen on any client device accessing the same mailbox.
  • The server can be searched for specific messages based on different criteria. This allows the user to download only the messages they want.

Switching from POP to IMAP


Switching your Cox.net POP email to an IMAP server requires the following:

  • Set up an IMAP email account using the same email address associated with the POP settings. See Resources for Setting Up Cox.net Email for additional assistance.
  • Delete the POP email account.

When changing your Cox.net email from POP to IMAP, you can potentially lose email messages. If a message does not appear in an email account, it may be due to one of the following reasons:

  • A configuration issue with IMAP or POP access
  • Settings applied to incoming mail, such as filter or forwarding
  • Deliberate or accidental human action, or a comprised account
Before deleting the POP email account, it is recommended that you back up your current messages.

The most common reason for missing email is that the message setting, Leave Messages on Server, within your email client is not enabled when using POP mail. Most email clients can have a POP and IMAP enabled mailbox that share the same account credentials.

To prevent losing email when switching from POP settings to IMAP, be sure that the option for Leave Messages on Server is enabled.


What is the difference between POP and IMAP?

Unlike POP, IMAP offers two-way communication between cox.net Webmail and an email client. This means when you log in to Webmail using a web browser, the action you perform on an email client will automatically appear in Webmail. If you read an email in your email client, the email will display as read the next time you log into Webmail.

IMAP also provides a better method to access email from multiple devices. If you check email at work, on your mobile phone, and at home, IMAP ensures that new mail is accessible from any device at any given time.

How do I sync my cox.net email on all my devices?

All of the devices you use to check your Cox.net email must be configured for IMAP. If any device is configured for POP, the messages can potentially become out of sync.

Why do I see multiple “Sent” folders on my mobile device?

Some email clients - Outlook 2010, Apple Mail, Windows 7, and Android 4.1 - create default folders, such as Sent and Trash, that are different than the cox.net default folders.

Why am I not getting any search results when I know the email exists in my folder?

You may have trouble searching for an email if your folder has more than 1,000 items. This is based on default settings on some mobile devices. You can log into http://webmail.cox.net and search for emails there.
