To fix the same messages coming from a POP account again and again:

• >> Step by Step Screenshot Walkthrough

• Open your Outlook Express store folder in Windows Explorer.
• Click on the file named "Pop3uidl.dbx" with the right mouse button.
• Select Delete from the menu.

Since Outlook Express has just lost even the rest memory of which mail it has already seen, expect all mail still on the server to be retrieve the next time you click Send/Recv. After that, mail retrieve should return to normal, however.

All duplicates already received can be eliminated fast with a duplicate removal tool.

Hey there,

The most probable problem is that your e-mail accounts SMTP settings are incorrect. Check what the SMTP settings are supposed to be with your e-mail provider then update these in the account settings within Outlook Express. For more details on how to do this, feel free to contact me again.

Hope this helps :)

In the Outlook Express folder delete Old.dbx change the file name from Old.bak to Old.dbx
Also, if this does not help, try as a last resort use a special software.

If you can send but not receive then check your server names. In Outlook Express, click on Tools, Account Settings, highlight your account. Click "Change" to gain access to the settings. The Incoming and Outgoing server names are determined by your Internet Provider. Place the provided names in the fields, and restart Outlook Express.

you can print the path needed to send mail
also you must use Internet Explorer to send mail in Outlook, if you use another search engine, it will not work.

Plz disable ur internet, close ur outlook without sending, then open again & if sending receiving then cancel immediately, now u can delete ur e-mail from outlook.

there are so many back up softwares on Outlook Express. Feel free to find them on download.com - this is the automatic and easy way. e.g. Outlook Express Backup, Outlook Express Recovery etc. 
The hardway - 
Another way is to create a folder on your outlook and name it archive or whatever u want it.. this is where you put the old emails/ the not so important ones.. then after that find the folder where it stores the .dbx files. It's called Store Folder.. Then just copy it to another folder then delete that on your outlook express.
If you can't seem to get it.. just use the softwares readily available for use on download.com
