Tip & How-To about Microsoft Outlook Express

Duplicate emails in Outlook Express?

When Outlook Express is configured for POP3 mail access it uses a file called pop3uidl.dbx to keep track of which message have been downloaded so that it can download only new messages. Sometimes this file becomes corrupted which results in the same messages getting downloaded again. So we will need a different copy of this file. Please do the following to recreate it:

- In Outlook Express click on Tools and Options.
- Click on maintenance tab.
- Click on Store folder button.
- It will open a small window with a path to the store folder.
- Copy the whole path.
- Click on start and Run.
- Click inside the run box and press Ctrl+V, it will paste the whole path we copied.
- Click on OK. It will open the store location.
- Close Outlook Express.
- In the folder that was opened, locate the pop3uidl.dbx file and right click on it and select rename.
- Rename that to pop3uidlold.dbx.
- Open Outlook Express and you will no longer receive any duplicate messages.

If you are using IMAP account, that can happen if your IMAP account is the default mail account and OE is configured to both open directly to the Inbox (which downloads headers automatically) and check for new messages when starting (which also downloads headers automatically). To stop the duplicates, simply choose one option or the other, but not both:

In Outlook Express click Tools > Options, then
1. Remove the check mark for When starting, go directly to my ‘Inbox’ folder
OR
2. Remove the check mark for Send and receive messages at startup.

If you already have duplicates showing, click Tools > Synchronize Account or Synchronize All.

outlook express mail keeps repeating- over and over


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

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.

i cannot open dbx files


Hi,
If you cannot open the .dbx file, you need to have Outlook Express installed on your computer. Usually outlook Express is the default email client for Windows XP. http://www.dbxconverter.com/ you can try to use this link to get teh converter of .dbx files to .pst files that you can use and read using Microsoft Outlook (Third Party) or Windows Mail (default for Vista) Windows Live Mail(Windows 7).
Cheers!!

I keep getting the same e-mail messages over and over; thus am not receiving any new mail. Plus, just have to keep deleting repeating mail.


If you are in Outlook Express :

To remove the option ‘leave messages on server’ click on Tools, Accounts, a box will open up labeled Internet Accounts, be sure you are on the tab labeled ‘Mail,’ highlight the mail account, next click on properties. Once you click on properties, you will click on the Advanced tab. At the bottom of the Advanced page you will see a section labeled ‘Delivery.’ If there is a check mark in the box next to ‘Leave a copy of messages on server,’ remove that check mark. If there is not a checkmark in the box, proceed to the next resolution.

To fix the problem, simply delete the "Pop3uidl.dbx" file, do a search/find for "pop3uidl.dbx". The next time you check for mail, all the messages on the server will be downloaded again, but a new "Pop3uidl.dbx" will be created that should work properly on subsequent mail checks.
