Emails are saved in a standard RFC 822 EML format as they are received from the customer’s email server.  This includes all headers and attachments as they were in the original, raw email.  We also offer the ability to download from the Search tab to an Outlook PST format which you can then import as a folder into Outlook.  The Export button is at the bottom of the Search Filters (below Date Range, Addresses, Message Type, Mail Nature, Randomize… all the way at the bottom of that section.)
