Wodewick, let's assume you're using Windows XP.
Your Inbox.dbx should be here:
C: \Documents and Settings\fobotcso\Local Settings\Application Data\Identities\{.......}\Microsoft\Outlook Express.
If it doesn't exist disregard the rest of this...
If it's there, carry on.
In OE, create a new Inbox Folder if it hasn't already re-appeared automatically.
Go back to the above folder and there should now be a new file - Inbox.dbx(1).
Delete it
Rename the old file from Inbox.dbx to Inbox.dbx(1)
You should now be able to read the files in your Inbox in OE.
PS: 900 e-mails in one folder is asking rather a lot from OE and, anyway, losing them all in one go does rather point to the advisability of distributing them before backing them up.
But I have recently worked on a PC where the Inbox had 1300 e-mails and was 173MB in size. So, for the addition of just one e-mail, the whole 173MB had to be backed up - every time!
