Cannot send emails via outlook express, but can receive

can't send emails via outlook express but can receive.

Get following error message

The message could not be sent because the server rejected the sender's e-mail address. "The sender's e-mail address was..., Server:...', Protocol: SMTP, server response: ' 451 4.3.2 Please try again later ', Port: 25, secure (SSL): no, Server error: 451, error number: 0x800CCC78

It is only to start.

My email [email protected] mail.optusnet.com.au Server address

Took the floor to the supplier (Optusnet) & they say it's a problem to microsoft

And this is your address which is rejected, correct? This happens if you try to send a message to yourself?

My money is on a server problem that will clear up on its own, but you can try a few things to eliminate that he's on your side.

1: Disable the analysis in your e-mail anti-virus program.  It is a redundant layer of protection that devours the CPUs, slows down sending and receiving and causes a multitude of problems such as time-outs, account setting changes and has even been responsible for the loss of messages. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:
http://www.oehelp.com/OETips.aspx#3

Why you don't need your anti-virus to scan your email
http://thundercloud.NET/infoave/tutorials/email-scanning/index.htm

Note that for many AV programs, it may be necessary to uninstall the program and reinstall in custom Mode and uncheck e-mail scanning when the option is available.

2: Create a new sent items and Outbox.

Spend most of your messages out of the Inbox and then create new folders to send and sent items box after having moved the messages you want to save to a local folder that you create.

Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.

In Windows XP, Win2K & Win2K3 the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.

With OE closed, find the DBX files for the items in the Outbox and sent and delete them.  New ones will be created automatically when you open OE.

After you're done, followed by compacting your folders manually while working * off * and do it often.

Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.

General precautions for Outlook Express:

Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.

    Ok thank you. I received three messages from you, two of the demon and the other Hotmail.

    Hotmail has helpfully includes the originating IP address, so I was able to check further. There is no WHOIS data for it (a bad sign to start), but it is not in the CBL. Read this page to see why it is listed and take the appropriate action. Once you are convinced that your computer - and another using the same network - are clean, you can use the link at the bottom of the CBL page to remove from the list the IP address.

    I still don't know where FCMA comes into it, and diagnostic tests in the NDR is incorrect. It is not the content of the message that is at fault, but I suspect that the block list.

    Good luck!

  • Can not send message from Outlook Express 6, can receive ok.

    I can't send messages.  I have Outlook Express 6.  I can receive.  When I send it crashes, there is no error message, if I move the box (click and drag the blue banner) is like a ventilated on card game.  No way to process, I need Ctrl alt dlt on Outlook.  I have Service Pack 3.  The "sent" box is empty.  I have Comcast, I have called them and went throgh their Checklist (incoming & out of the server settings will and everything is correct.)

    Thanks, I'm back in business.  In addition to what you show in "General Precautions for Outlook Express" to understand why this happened.  I got a lot in the deleted items folder.

    Once again, thank you.  I really appreciate your time.

    You're welcome and thanks for posting back.

    The default main identity can become corrupted very easy because there a few registry keys more than user created files that work very well.

    The dbx file system is very fragile and also prone to corruption. By creating new identities, each single dbx file is new. Which have been the cause of the problem could have been determined by their replacement one at a time, bur which would have been a lot more time and a new identity is deeper.

    If you comply with security measures, you are much less likely to have this kind of problem in the future.

  • I can send emails on Outlook Express but I have not received email 5 days

    Please help me? I learned by the folks at Microsoft that my problem is in my mail exchange server settings. They suggested that I ask this question here for not paying additional fees. Any assistance in finding ways to fix the problem would be much appreciated.

    It is possible or likely that the MS person you correspond to got confused between the two as well.

    There might be corruption in the database account in OE that prevents the receipt of messages.  Try to go to file | Identities and setup a new identity.  That will make everything fresh and then add your account and see if it works then.  If so, use file | Import | Messages to bring them from the old identity.

  • Can't send emails in outlook express no. 0 x 800 CCCOB error any ideas

    can receive but can't send emails via outlook express or incredi mail error is not 0x800CCCOB

    Go to file | Identities and install a new identity and add your e-mail account to this identity after checking that you do not have conflicting antivirus (see www.oehelp.com/OETips.aspx#3).  See if the account works very well with the new identity.  If this is the case, then go to file | Import | Messages to bring them from the old identity.

  • I can receive and answer emails on outlook express but I am unable to store a contact or add sender to address book.

    original title: outlook express

    I can receive and answer emails on outlook express but I am unable to store a contact or add sender to address book. I get the error message "an error has occurred. Outlook Express could not add the sender to the address book"

    Office has not OE and Outlook.  Are you sure you are using OE and not Outlook?

    The default location of the address book (wab file) is C:\Documents and Settings\ [username] \Application Data\Microsoft\Address Book\username.wab

    The location is hidden, so you must go to control panel | Folder options | Discovers and check the box to include the display of the hidden files and folders and uncheck the option to hide the extensions of the file types that you want to know.  Then see if you can browse to the location of the wab file and find him then.
