EarthLink comes with the EarthLink TotalAccess Mailbox Export Tool, which exports EarthLink emails to some email clients like Windows Live Mail. EarthLink TotalAccess exports mailbox items into its proprietary *.DAT files, which open only in the EarthLink mail program. It can also export emails as CSV (Comma Separated Values). But, CSV file does not include email attachments, images or objects. So it cannot fully export all email items to major email clients like Outlook or Thunderbird.
But, with the help of our EarthLink Email Backup Software you can easily export mailbox items to popular email formats, document formats or mail clients. This software provides 30+ file formats including direct option to email clients like Office 365, Thunderbird, Outlook.com, Zimbra, Lotus Notes etc. The major file formats this application allows to export EarthLink emails are PST (Outlook), EarthLink to MBOX (Mac Mail), EarthLink to EML (Windows Live Mail), EarthLink to EMLX (Apple Mail), EarthLink to MSG (MDaemon, Outlook single message files), EarthLink to PDF, EarthLink to XPS, EarthLink to DOC (Microsoft Word), EarthLink to RTF (Rich Text Formatting), or EarthLink to HTML files.
So, it is a better choice to export EarthLink emails than the EarthLink TotalAccess Mailbox Export Tool.
