    Outlook Express: Error number 0x800CCC0B

    If I have my OE with my mail everything works beautifully, but what if I want to send, it bangs me this error message to the ears:

    An unknown error has occurred Subject "--", Account: 'my account', Server: 'smtp.puretec.de', Protocol: SMTP, Port 25, Secure (SSL): No, Error Number: 0x800CCC0B

    The message could not be sent because the server is the e-mail address of the sender has not accepted. The e-mail address of the sender is "my address" Subject ... ... ... Account Server Response: "530 Authentication required" ... Server Error 530, Error Number: 0c800ccc78

    Who can help me?

    Hi,

    Solution for Error code 0x800CCC0B :

    These error messages occur if Microsoft Outlook or Microsoft Outlook Express can not establish a connection to the mail server.
    These error messages usually due to one of the following causes:
    - Incorrect Account Settings
    - Bad software configuration of personal firewall
    - Antivirus Software
    - A faulty modem
    - Size of Maximum Transmission Unit (MTU)
    - Outlook Express has been removed from the computer or the installation is corrupted
    - The user profile in Outlook is damaged
    - An email from the POP3 server is damaged

    Hi,

    Go to:
    - Accounts
    - Properties
    - Servers
    Then check the box that says "My server requires authentication" is checked.

    Enter your Account Name and Password.
    Then click "Apply" and then "OK"
    Restart Outlook.

    This error does not have the original server on which your site is hosted Possible causes:

    1. Wrong configuration of email client
    2. Your ISP blocks port 25
    3. DNS problem at your ISP

    The problem can be solved in general by:

    1. restarting your computer
    2. Check that Outlook (or use your email client) is checked "SMTP: My server requires authentication". Check accuracy of data and access to email.
    3. Temporarily disable antivirus / firewall your
