What is the file format .edb used with?

• A. Microsoft Exchange
• B. SQLite
• C. Outlook PST
• D. Windows Event Log

Answer: (A)

.edb is the Exchange Database file used by Microsoft Exchange Server's Information Store. It employs the Extensible Storage Engine (ESE) and holds mailbox data such as emails, calendar items, and other mailbox content. In a forensic investigation, this format is encountered on Exchange servers and requires Exchange-aware tooling to access and parse the mailbox data. This format is distinct from other common formats: SQLite uses .db or .sqlite, Outlook data is stored in .pst, and Windows Event Logs use .evtx (or .evt).
