Need of Windows Mail backup

Since Windows Mail saves your precious emails, it is of great importance to create a backup for them. You may choose to backup Windows Mail to external hard drive for the following reasons:

  • Protect emails from computer errors. Those emails saved on your computer may suffer from virus attack, hard disk failure, system corruption and other unexpected errors.
  • Save email client space. Every email client has a limit to which they can hold emails. If your emails are near the limit, you can backup some mails to an external drive and delete them in the client.
  • Move emails to a new computer. You can view your emails on a new computer easily if you have backed up them to an external hard drive.
