Mail applications typically come with Windows 8 and Windows RT, but do not support the addition of e-mail accounts that use POP (Post Office Protocol). WIN8E 800 million Web alerts if your e-mail account uses POP and you want to access the account on your computer, here are some options:
1. If you wish to use the mail application and keep your current account, please contact your email provider and ask if you can change your account to use IMAP (Internet Message Access Protocol) or EAS (Exchange Active Sync).
This change is especially useful when people want to get their e-mail messages in a variety of ways (phone, personal computer, working computer, and so on), because they are better than POPs in keeping track of new messages, unread and deleted items, and automatically saving your messages. Please note that some providers may charge additional charges for the replacement operation.
2. Use your email account provider's website to collect mail. For example, if your e-mail account belongs to Contoso, please visit www.contoso.com and log in.
3. Find applications in the Windows store that support e-mail accounts that add the use of POP.
If you want to use a mail application and want to switch to a new e-mail account, you can stop using the previous account and start using web-based e-mail accounts (such as Outlook.com, Gmail, or Yahoo!).
If the original account's mail is stored on your computer, but you want to get these messages in the new account, you can register a outlook.com account and then use the mail migration add-in to add it. After you move a message to a new web-based account, you can add the account to the mail application.
