How do I save emails through cable into a folder on my hard drive?

Do you normally use the web client for email or a standalone application like outlook or thunderbird?

He is using the cable company website. He saves them in folders he can create in their website.

It looks like they give you POP/IMAP access to your email a account. I would probably just use Outlook (Directions Here) and then export them.

Depending on how many there are it might just be easier to forward them to a new email account.

There are maybe 400 of them. He was worried about putting them into outlook, because it would be a huge number of them at once.

Shouldn’t be a problem. I have done it with 20K+ emails. Just go out for some Burger King while it does its thing.
