Switching from POP to IMAP

To prevent losing your Email or Email folders when switching from POP settings to IMAP:

If you had "Leave messages on server" enabled since initial Charter.net Email setup, follow these steps:

  1. Create an imap enabled account for the Email address you want to switch to within same Email client. (Most modern Email clients can have both a POP enabled and IMAP enabled mailbox/account that share the same account credentials)
  2. Delete your pop mailbox account from the Email client

If you did NOT have "Leave messages on server" enabled since initial Charter.net Email setup or unsure, follow these steps:

  1. Ensure that you have the option "Leave messages on server" checked in your account settings on your Email client.  This setting should be available under "advanced settings" or something similar, depending on the client.
  2. If you have the option to disable Send/Receive in your Email client, disable it to ensure no new messages are delivered to the POP enabled mailbox/account.
  3. Create an imap enabled account for the Email address you want to switch to within same Email client.  (Most modern Email clients can have both a POP enabled and IMAP enabled mailbox/account that share the same account credentials)
  4. Move messages and/or folders by creating a storage or data folder (Outlook calls these PST), then drag and drop the messages/folders you wish to keep into the new folder.
  5. When you have moved over all of your Emails/Folders you can delete your pop mailbox
