Yes, there certainly is!

1. Create a new folder on the desktop named Exported Mail (on the Finder, click File, and then click New Folder).
2. Start Outlook Express.
3. If necessary, resize the Outlook Express window so that the desktop is visible.
4. Click the folder that contains the messages that you want to export (for example, the Inbox folder).

Use RecoveryFix for Outlook Express to recover dbx file which may get corrupted due to some virus or due to header corruption of dbx files or sometimes the media where dbx file is stored get corrupted. This tool recover data even from password protected dbx files. Have a look at this tool http://www.outlookexpressrepairtool.net/

Unfortunately, there is no easy way to disable this. The best you can do is delay the messages, or avoid them altogether. I have listed both methods below, and would suggest number 1 over number 2:

Method #1 - In Outlook Express, click on Tools>>Options>>Maintenance. Click on the Cleanup Now button, and then Compact. Doing this regularly will keep you from getting the messages.

Method #2 -

• Open the registry (click on Start, Run, type Regedit and click Enter).
• Browse to HKEY_CURRENT_USERIdentitiesyour identitySoftwareMicrosoftOutlook Express.0.
• Look for the registry value titled Compact Check Count. This typically has a value of between 1 and 5, which means Outlook Express will check every 1 to 5 times to see whether you need to compact. Double click on the item, and set the number to 100, so you will only see the message every 100 times you open Outlook Express.

I have put details of copying over addresses and the emails for both Outlook express and Outlook.Hope this helps.

Outlook Express
In Outlook Express, select File --> Export and select Address book. I recommend that you use a comma-separated values (CSV) format as it's more portable and can be recovered if something happens since it's just a basic text file. Copy that onto the new computer, choose File --> Import, and select the CSV file. That should do it!
Backing up email is more difficult, however.
Here's the basic process in Outlook Express: Under Tools --> Options, click the "maintenance" tab. This will tell you where your email is stored. Now copy all of those files onto your new computer (if you make a CDROM you'll have a nice permanent backup too) and then put them in the exact same folder on the new system (while you aren't running Outlook Express). Restart the app and you should have all your mailboxes intact.
Outlook does have an appropriate archive/restore function too, if you want to try that instead. Under File, select Import/Export. Select "export to a file," then select the mailbox that you want to back up. If your mailboxes are like mine, this will produce a fairly large file, depending on the size of your mailbox. Copy these exported files onto the new computer, then use File --> Import/Export --> Import from a file and you should have the mailboxes on your new system.
Outlook
You'll have to export the Address Book from the computer then import it into Outlook on the new computer
1) On your desktop click File --> Export --> Address Book
2) Select the Comma Seperated Values (Windows) as your output format
3) Select the folder you want to export - in this case Contacts
4) Type a name for your file - example: addresses
5) Be sure there is a checkmark next to Export then click Finish
This is the important part: You'll need to copy or save the file to a flash drive or floppy. Alternatively, you can email the file to yourself or burn on CD if you don't have a floppy or flash drive available. Either way the file needs to be transfered to your new laptop.
1) On your laptop open Outlook and click File --> Import --> Import from another file or program (this varies depending on your version of Outlook)
2) Select Comma Seperated Values (Windows) - the same option you selected when you exported
3) Click Browse to retrieve the file you exported
4) Choose either replace, not to duplicate or duplicate under the options menu
5) Select destination folder - since this is your address book you would click Contacts
6) Be sure there is a checkmark next to Import then click Finish

Have a look at this follow the instructions it should make it all better.

MailNavigator can cope with the task of restoring out-of-order dbx files when Outlook Express itself cannot read them and when a range of other programs are not capable of restoring the information contained in these files. These situations can happen because of viruses, computer breakdown, power interruptions and many other reasons, leading to errors in the file system.
If your computer crashed, first of all you should make sure you have backup copies of your dbx files as well as of all other important data. It's good if you make backup copies of your data on a regular basis. But, unfortunately, in our experience situations are often encountered where there is already nothing to restore.
The process of data recovery from dbx files includes two stages:

• Search and read the dbx files in MailNavigator.
  
• Export the restored messages back to Outlook Express.
  

If your Outlook Express program is properly installed and tuned, MailNavigator will automatically find the dbx files from the information in the systems register. In this case you can load the dbx files from the Information Retrieval page by double clicking on each of them. Or search for messages in these files using the search system.
If MailNavigator cannot automatically determine the location of the dbx files (for example if these files are on a CD), first you have to find them using search tools, and then load them into MailNavigator using the menu command:
File | Load External Mailbox...
Once you've read the messages, select the ones that should be exported back into Outlook Express. You can use various filters to select the messages. If you want to export all the messages browsable in the Navigator at once, use the menu command:

Message | Select All
Having selected the messages, export them using the menu command:

Message | Save as...
In the opened dialogue box, indicate the file and export path, and choose the file type: Eudora mailbox.
When the command is executed, there will be files in the export directory with extensions .toc and .mbx, and also a file descmap.pce. If there are attached files in the exported messages they will be saved in the subdirectory Attach.


Once the mailbox in Eudora format is created, open the program Outlook Express and use the menu command:
File | Import | Messages...

In the opened dialogue box, as the program from which the message is imported, select: Eudora Pro or Light:

In the next dialogue box indicate the directory in which you put the messages from MailNavigator at the export stage:

Further, if Outlook Express finds mailboxes in this directory, it will suggest you select one of them for import:

All that remains to do is to press the Finish button, and a folder containing the imported messages is created in Outlook Express. hope this helps
