Tips to Prevent Outlook Express Messages from Disappearing

Outlook Express DBX file structure is prone to corruption for various causes. This is the reason why you often observe email messages disappearing from OE folders. The most significant reasons causing this issue are antivirus software scanning and background compaction. Ironical but true, if an antivirus software is configured to scan Outlook Express message store, this can trigger corruption. Also, the background compaction feature of Windows prior to Windows XP SP2 can corrupt the folders. So, the best practice is to turn off these features and hence, prevent any Outlook Express Recovery solution requirement while folder corruption.

Turn Off Antivirus Software Scanning

An antivirus software can corrupt the message store or a folder when attempting to delete any message that contains a potential virus. This also applies to anti-spamware applications that somehow interrupt with the working of Outlook Express. Thus, you should disable email scanning using an antivirus software.

Viruses usually come as email attachment. Thus, even though you disable the antivirus scanning for incoming or outgoing emails, you are still protected. This is because when you try to open a virus infected attachment, the software will detect it and will warn you against it.

Turn Off Background Compaction

To remove the wasted space that generates whenever you delete or move a message file, Outlook Express comes with a default enabled feature called background compaction. Whenever the application is left idle for some time, it starts compacting the folders. The process slows down your system and consumes 100% of CPU resources. But it can result into folder or store compaction, if interrupted.

You can disable the feature under Tools Options Maintenance option of 'background compaction' and compact the folder whenever required manually.

Windows XP SP2 removes this feature, though not completely. It now starts compacting the folder when you open and close Outlook Express 100 times. At 100th time, you will be prompted to compact the folders.

Outlook Express Messages are Delivered to Drafts Folder

Outlook Express is not a completely reliable database program and can have problems with its mail folders, the *.dbx files. For this reason alone, you should always maintain a backup of your important emails. This will prevent you from data loss consequences that might occur due to mail folders' corruption. However, if backup fails to restore, you will need a Outlook Express Recovery solution to repair the corrupted files.

For example, you might come across issues when you start receiving new email messages in Drafts folder instead of default Inbox folder. All other email operations work well, except that the emails are delivered to OE Drafts.dbx file.

Cause

The basic reason for such issues can be any of the following:

1) You have configured Outlook Express to use a rule that directs all the incoming email messages to go to Drafts folder.
2) Folders.dbx file is corrupted or damaged. It is the master index file of Outlook Express Store Folder and can affect other .dbx files as well if goes missing or damaged.

Solution

To solve the described issue, you need to follow these solutions:

1) You should check if the rule exists that might be directing the incoming mails. For this, open Outlook Express, go to Tools and then Message Rules. If no such rule is there, you can alternatively create a new rule to send the receiving emails to Inbox folder.
2) For fixing corrupted Folders.dbx file issue, you need to recreate it. Locate the file using Windows Search or Find option, right-click the file and click to rename it to Folders.old. Outlook Express will create a new Folders.dbx file, the next time when you will start the application.

If you find the other .dbx file(s) corrupted, you can rename them too by following the same procedure as above, provided you have a valid backup. However, you can repair the corrupted .dbx files by using DBX Repair software. The commercial Outlook Express Recovery software are most suitable applications that can repair and restore a corrupted .dbx file by using powerful and safe scanning algorithms.
