What artifacts are commonly found in email forensics, and how do PST/OST files relate?

• A. Email headers, body content, attachments, and metadata; PST/OST files store local copies of mailbox data
• B. Only subject lines
• C. PST/OST files are irrelevant
• D. DNS logs contain emails

Answer: (A)

Email forensics focuses on reconstructing what happened with messages by examining both the content and the signals that show how messages moved. The artifacts investigators typically look for include the headers that reveal who sent the message, who it was to, the subject, dates, and the path the email took, the actual body content, anyAttachments, and metadata that describes timing, modification, and mailbox properties. Together these pieces show what was sent, when, and by whom, as well as how it traveled through systems. PST and OST files matter because they are primary local stores of mailbox data on a computer. A PST file contains messages, folders, attachments, and related items from a mailbox, while an OST file is a cached offline copy that synchronizes with a server-based mailbox. In investigations, examining these files can recover emails that may no longer exist on the server, reveal deleted or recoverable messages, and provide the associated metadata and timing needed to piece together conversations and timelines. They complement server-side evidence and help you build a complete picture of email activity. Relying only on subject lines would miss the actual content and context of the messages; treating PST/OST as irrelevant overlooks a key source of mailbox data on the host; and DNS logs do not contain the emails themselves, just information about domain lookups used in delivery.
