An EDB file is the Exchange database files stored in Microsoft Exchange Server. Each Exchange Server creates one EDB file containing all the mailboxes (emails, calendar, contacts, attachments, tasks, etc.). The data stored in Exchange in the form of EDB file accessed by Extensible Search Engine (ESE) or JET Blue.
ESE is an indexed and sequential access method (IASM) to access the data stored in the Exchange Server.
