Emails, calendars, notes, journals, etc. you create using your MS Outlook account are stored in your mailbox on Exchange Server in .EDB and .STM files.

Recovery Modes

Exchange Server repair and recovery software is embedded with three different recovery modes. You can select any of these recovery modes to repair or rebuild the damaged database depending on the corruption condition and intensity. Exchange Server is equipped with following recovery modes:

Automatic Analyze and Recover Mode: This is the fastest mode and is recommended to be used when there is less corruption in Exchange database file. Mailboxes recovered using this mode are saved in .PST format at the defined location from where you can directly access them using MS Outlook.

Advance Scan Mode: This mode is slower in comparison to Automatic analyze and recover mode. You should use this mode when the Exchange database file is highly corrupt or the results of Automatic analyze and recover mode are less satisfactory. Mailboxes recovered using this mode can be directly accessed with MS Outlook as this mode saves the recovered mailboxes in .PST format.

Rebuild Corrupted Database Mode: This mode helps you to achieve the clean shutdown and consistent database state after the database has been damaged due to Dirty shut down. In that situation, you need to rebuild the damaged Exchange database and mount the new database on Exchange Server.

This mode of Exchange Server software facilitates you to rebuild the Exchange database file from damaged database file. The new database file is saved at the user-defined location in a folder, which is automatically named in the format- Day_Date_Time. The format Day_Date_Time refers to current day, date, and time. In the same folder where rebuild Exchange database file is saved, a batch file, Verify.bat is also created.

The Verify.bat file helps you verify the healthiness of the new database file. On double-clicking the Verify.bat file a .txt file will be generated in which output of the Verify.bat file is saved. You can find the .txt file in the same folder where Verify.bat file is available. In .txt file internal structure of the new Exchange database file is saved that represents the database healthiness. But, if there is some problem in database repairing then instead of the database structure, an error message representing the problem in database repairing will be saved in .txt file. In case, you see an error message in .txt file then find out the reason for that error message, resolve it, and then again try to rebuild the database. After that, you can mount the new database file on Exchange Server.
