Basic Method to Change Yahoo Email to IMAP

One way people usually do this is by using an email client like Outlook or Thunderbird. These programs let you add more than one email account. After that, you can simply move or copy emails from your Yahoo mailbox to the IMAP account.

Simplified steps to transfer email Yahoo to IMAP account:

Step #1: Turn On IMAP in Yahoo Mail

  1. First, sign in to your Yahoo Mail account.
  2. After that, go to Account Settings and open Account Security.
  3. Next, if two-step verification is turned on, create an App Password. Users will need this while adding the account to Thunderbird.

Step #2: Add Yahoo Mail to Thunderbird

  1. Firstly, open Thunderbird on your system.
  2. Then, go to Account Settings and select Add Mail Account.
  3. Now, enter your name, Yahoo email address, and the app password you generated earlier.
  4. Later, hit Continue so that Thunderbird can detect the settings automatically.
  5. If it asks for manual settings, enter these details:
    1. Incoming Server (IMAP)
      Server: imap.mail.yahoo.com
      Port: 993
      SSL: SSL/TLS
      Authentication: Normal password

                 b.  Outgoing Server (SMTP)
                      Server: smtp.mail.yahoo.com
                      Port: 465 or 587
                      SSL: SSL/TLS
                      Authentication: Normal password

Once everything is entered, click Done. Thunderbird will start syncing your Yahoo Mail folders.
