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.
Note
If a .msg
file is attached to an email and sent from a Windows Outlook
client, the email will actually be sent as a .eml
file. So, users can send
email samples without needing to worry about the file format.
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)
Create a new email and leave it open a separate window.
Drag the email from the inbox or other folder and drop it in the message of the draft.
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.
