5. Frequently Asked Questions (FAQ)

1. What does Stellar Repair for Exchange do?

The software repairs corrupt EDB files and restores all its data such as e-mails, attachments, contacts, calendars, notes, tasks and journals. Stellar Repair for Exchange provides the preview of all the scanned data and gives options to export data to Live Exchange, Public Folder, Office 365 or save in PST, MSG, EML, RTF, PDF and HTML format.

2. What is the difference between an EDB file and a STM file?

The .EDB file is the main repository for the mailbox data. The STM or streaming media file is used in conjunction with the .EDB  file to comprise the Exchange database. Both files together make up the database, and as such, they should always be treated as a single entity. Typically, if you perform an action on the EDB  file, the STM file is automatically included. The purpose of the STM file is to store streamed native Internet content.

When you install a new Exchange server in an organization, two data stores are created automatically: a default mailbox store and default public folder store. Two database files are associated with the default mailbox store:

Priv1.EDB: A rich-text database file containing message headers, message text, and standard attachments.

Priv1.STM: A streaming internet content file containing audio, video and other media that are formatted as streams of Multipurpose Internet Mail Extensions (MIME) data.

The STM file houses Internet content message streams as defined in Request for Comments (RFC 822), and the EDB file contains messages that are in MAPI format (Rich Text Format).

When an Internet mail message comes into the Exchange information store, the body of the message is saved in the STM file, and the header information (From, To, Cc, Time Sent, and so on) is repaired to Rich Text Format (RTF), and then stored in the EDB file.

3. I am not able to find my EDB file, how do I locate it?

5. How much time will the Stellar Repair for Exchange Software take to repair an EDB file?
