If you want to save your Yahoo Mail messages to your computer in a format that works with Outlook or other email programs, there are two main ways to do it: the manual way and the recommended way.

Manual Way:

1. First, you need to set up your Yahoo Mail account in an email program like Outlook or Thunderbird.
2. Then, in that email program, you can save your Yahoo emails in a special format called PST.

However, this manual method has some drawbacks:

• It can take a lot of time, especially if you have many emails.
• If you're not experienced with email programs, it might be tricky.
• There's a risk that your data could get lost or damaged.

Recommended Way: Instead of the manual method, it's often better to use a special tool like the Cigati Yahoo Backup Tool. Here's why:

• This tool can quickly and accurately save lots of emails, even if you have a ton of them.
• It reduces the chances of losing your data or having it messed up.
• You don't need to be a tech expert to use it.
• It can save your emails in different formats, including PST, which is what you need for Outlook.

In short, while the manual method can work, it's not as efficient, safe, or easy as using a tool like Cigati Yahoo Backup. So, if you want a smooth and secure way to move your Yahoo Mail to PST (Outlook), the recommended method is your best bet.
