Key features
Convert EML files from Windows Live Mail and other clients
The tool accepts EML files exported from Windows Live Mail, Thunderbird, DreamMail, Outlook Express, The Bat!, Apple Mail and others. It also handles EMLX files.
Convert only the emails you pick
After you add files, the full folder tree loads and you tick the folders you want. An advanced filter narrows the job by date range, sender, recipient or subject, and lets you exclude folders such as Junk or Trash and skip empty folders.
Keep attachments, metadata and folder hierarchy
Sender and recipient addresses, sent and received times, subject lines and attachments carry over, and the original folder hierarchy is preserved.
One PST per user
If you have ten mailboxes of EML files, the separate PST per user option produces ten PST files.
Runs without Outlook installed
It is a standalone utility, so you don't need Outlook or any third-party application on the machine doing the conversion. The resulting Unicode PST opens in current and earlier Outlook versions, including 2010.
Who it's for
You'll get the most from it if you are moving an old Windows Live Mail archive into Outlook, or consolidating EML exports from several mail clients and several users into PST files.
