Email samples and Outlook clients

Microsoft Outlook for Windows

If you save an email to a file using Microsoft Outlook on Windows, it will save the file in a proprietary Microsoft OLE format with a .msg extension. There are tools like msgconvert that make an attempt to convert a .msg file to a standard RFC 822 .eml file, and mailsuite will attempt to use this tool when encountering a .msg file if it is installed on the system. However, anomalies are introduced during conversion that make the results unsuitable for forensic analysis.

Instead of using msgconvert, use one of these other Outlook clients.

Microsoft Outlook for macOS

Drag the email from the inbox or other folder and drop it on the desktop. Attached emails can be saved to a file like any other attachment.

Outlook Web Access (OWA)

1. Create a new email and leave it open a separate window.
2. Drag from the inbox or other folder and drop it in the message of the draft.
3. Download the attachment that was created in step 2

Emails that are already attached to an email can be downloaded from OWA like any other attachment.
