Extensible Storage Engine Database (EDB) file is created by the MS Exchange, which stores the mailboxes and public folders in an organization. The EDB file stores all mailbox items such as emails, attachments, contacts, calendar items, notes, etc. It also stores deleted mailbox items, which can be restored if a user deletes them accidentally.

You can open the EDB file in MS Exchange by mounting it. However, if the database is offline, you cannot open or access the mailboxes. In such cases, you can either mount the database to the Exchange server or use a free EDB viewer to open and view the mailboxes and mail items stored in the EDB file.  

A free EDB viewer such as Stellar Converter for EDB comes handy when the Exchange server is down or unavailable. It saves the user from rebuilding and investing time and effort in setting up an Exchange server just to view the EDB files.

In this guide, we have discussed the steps to open and view EDB file with free EDB viewer tool that does not require Exchange setup or any permissions. The tool can help you view both, hosted and offline EDB files.
