What is EDB File Extension: How to open .EDB Without Exchange?

Exchange Server creates an EDB file to store the mailbox data like emails, contacts, calendars, notes, tasks, etc. The Exchange Server uses extensible Storage Engine (ESE) to read the data from the EDB file. We can say EDB file as the central repository where data of every mailbox of Exchange Server is stored.

What is the Full Form of Exchange EDB File?

EDB file stands for Extensible Storage Engine Database File, which uses B-Tree data structure to access the data efficiently. This EDB file stores the messages and data sent and received by Outlook, and that is why the EDB file is sometimes referred to as the MAPI-Based Database.

Different Types of EDB Files?

Priv.EDB: Whole private communications between mailboxes are stored in the Priv.EDB file.

Pub.EDB: The Pub.edb file stores public communication like messages shared to a public group.

STM File: The STM file stands for Streaming Database and stores the multimedia content.

Priv.edb, Pub.edb and STM files are used in the Exchange Server 2000 and 2003. In Exchange Server 2007 and 2010, Priv.edb file is replaced with MailboxDatabase.edb and Pub.edb file is replaced with PublicFolderDatabase.edb

With the release of Exchange Server 2013, both these files (MailboxDatabase.edb and PublicFolderDatabase.edb) are merged with the single file named as MailboxDatabase.edb and now only one file is used to store all this data.

What is the location of the EDB file format?

A different version of Exchange Servers Stores EDB file at a different location. Below is the default location of the EDB file based on the Exchange Server versions:

Exchange Server 2019/2016/2013

The default location of Exchange Server 2019, 2016, and 2013 is
