Outlook Express doesn't send e-mail. 0x800CCC79 error number

I'm moving from one computer to the other.  Both Internet Explorer 6.00.2900.5512.  I think I have all the same settings.  But my new computer doesn't send emails.  He received very well.  Can not answer.  Get the following error message (address of the recipient has been deleted):

The message cannot be sent because one of the recipients was rejected by the server. The rejected e-mail address was ' * address email is removed from the privacy *'. Subject 'test', account: 'embarqmail.com', server: "smtp.embarqmail.com", Protocol: SMTP, server response: 554 authentication has failed, have to login', Port: 25, secure (SSL): no, Server error: 554, error number: 0x800CCC79

That said, you're not authenticate correctly to the outgoing server.  Apparently, embarqmail requires that you authenticate to use their mail server.  On the "Outgoing server" tab of your e-mail account properties, check the box indicating that you must connect to the server.  It may also be true that embarqmail requires the use of one port other than 25, such as 465 or 587.  I saw it mentioned in a single reference that port 25 with authentication but no encryption should be used and in one other than port 587 with authentication and SSL must be used.  See the documentation that gave you your service provider or visit their help pages.

  • Outlook Express says cannot send e-mail because of lack of memory.

    With the help of OE I get a failure of shortage of memory trying to send an email of 353 MB.   I have a memory of 1.99 GB, XP3 and closed other programs.

    What is going on?

    aquaries

    I tried the solution of Steve and unresolved issue.  However, to instead a message of lack of memory the program OE plant.

    I tried to send smaller attachments in zip (79 M) records and the program when you select the attachment, it blocks.

    I tried a 10 M zip file and the method was successful.  So somewhere between 10 and 79M EO can respond and locks upward.

    Has OE code messages and he needs memory and time for it.  You take the system to its limits and there is not a lot we can do about it.  You're just going to have to be stuck with smaller attachments sending, or use some other file transfer protocol that does not have OE.  You could try webmail, if you have access to it.

  • Conversion of Outlook Express .dbx to Microsoft Live Mail issue box for receiving and sending files conversion

    I am able to convert most of my old Outlook Express files to Microsoft Live Mail, with the exception of the Inbox, and send files.   The two files are not empty.  My OS is Windows 7 64 bit.  The 'Files' file is located in the directory with the .dbx files.  Most of the files have been converted except these two.  The converted file sent.

    Can advise you on what to do to fix this?  I need the information contained in the Inbox, and send.   I have more access to Outlook Express.

    Best regards, Kat

    Unless you left no messages in the Outbox, it must be empty. Messages are just going through there on the way to your mail server.
     
     
    Folders.dbx is the "brain" of the system of dbx files and contains all the actual messages.
     
     
    Now regarding the messages from the Inbox, I don't know why they won't matter in Windows Live Mail. You compact the folders in OE before saving the message store? WLMail has great trouble with import of dbx files. How do you backup and transfer the storage of OE with dbx files folder?
     
     
    If you still have access to the machine with OE, it would be easy to fix. Given that you don't do it, you probably have two options.
     
     
    If you have professional, enterprise or ultimate edition, you can use OE in XP Mode. Who can import all the messages and then we can transfer it to WLMail.
