Re-create a new edb ? you sure? how about the data? users not worried about it??

1. how did you figure out if the .edb is corrupt?
2. do you have a recent back up?
3. what is the size of the corrupted edb database? doesnt it have any data??
4.  if you dont have back up - go for repairing the database - it will make the database back to clean shut down.

Agree that it would be good to obtain a bit more information about your situation first to ensure you get the best resolution, i.e. do you know what caused the database corruption?  Just want to ensure you don't end up fixing the database and then it happens again.

However to answer your question:

1. Make a copy of the corrupted/Damaged Exchange 2003 EDB & STM.  Best to copy it to an entirely different machine

2. Once you have secured a backup offline copy of the damaged Exchange 2003 Database files youe can delete the old EDB & STM or if you want to keep a local copy of the files until later just rename them i.e. if they are called Mailbox.edb and Mailbox.stm then rename them to OLD_Mailbox.edb and OLD_Mailbox.stm.

3. ok now go into the Exchange Management System and tell it to Mount the database and Exchange will complain that it cannot find the database files and IF you continue you will create new database files.

4. Say yes and new files will be created

5. No additional steps are needed, your mailboxes will be attached to the new database and your users can once again send and receive new emails.

Now that your users are up and running again you need to focus on getting back the historical email.  But before we look at that;

A. Tell me what caused this corruption
B: Before attempting to repair did you make a copy of the database files.
C: What actions have you taken so far to repair?

Followed guide from http://cpsolutions.be/wordpress/?p=244 to re-create new edb as customer will recover the data with third party software.

yes, the mailboxes auto-map to respective users.
