Do You Know Why DBX File Gets Corrupt?

Outlook Express is included with Internet Explorer as an e-mail and news client. Msimn.exe file is part of Outlook express. MSIMN is the executable file for Outlook Express. It is a default email application in Microsoft Windows. Msimn.exe should not be removed while you have Outlook Express open. MSIMN.exe will be located by default at c:\program files\outlook express\

The mails in outlook express are stored in DBX file. The store folder contains a set of DBX files.

Outlook folders are indexed by name folders.dbx. For example, Inbox.dbx, Sent Items.dbx and Deleted Items.dbx. Inbox.dbx, Sent Items.dbx, Drafts.dbx, and Deleted Items.dbx and so on. The DBX files stores within the "Documents and Settings" user directory. If you want to backup e-mail messages, you may copy these files to any other storage location or device."Folders.dbx" is the master index of the entire Store Folder .While copying DBX files from one Store Folder, you must copy Folders.dbx too otherwise you may unable to access Outlook Express.

Location of DBX file:
You can easily find the actual path to the DBX folders by clicking:
Tools>Options>Maintenance>Store Folder.

When the database increases in size, it may lead to DBX files corruption.

Here are some major reasons for DBX file corruption:
  • Invalid page fault in module Msoe.dll caused by MSIMN.
  • Invalid page fault in module Msoe.dll at address caused by MSIMN.
  • Outlook Express may not be installed correctly that leads to errors while starting Outlook Express.
  • Outlook Express could not be started because Msoe.dll could not be initialized.
  • Over sized DBX file above 2GB
  • Folder Compaction Interrupted
  • Accidentally system shutdown
  • Third party interaction
  • Corruption in DBX, MBX files
  • System Background Compaction
  • Virus Infection etc.
"Folders.dbx" is the master index of the entire Store Folder. In case it got corrupted then we cannot do anything in Outlook Express. The solution for this problem is to delete the corrupt file from the Store Folder. When Outlook Express will start, it will build a new "Folders.dbx" and re-index all DBX files that it finds in the Store Folder. It may slow down the system and also lead to severe data problems. To open corrupted DBX files, you need to convert DBX File to PST File. DBX file is a very important file in Outlook Express So, It is better to backup and clean up your emails periodically.
