Outlook Express Error 0x800CCC79: Not Able to Send Mail? Then Turn on SMTP Authentication

Are you experiencing difficulties with sending E-Mails in Outlook or Outlook Express? Does the program simply refuse to send your mail and report the error 0x800CCC79, for example?
Then the problem might be this: most providers now require you to log on to the SMTP server before you are able to send an E-Mail. In many cases it is enough to receive E-Mails and then send them. In these cases, the "POP before SMTP" rule is applied: the provider knows that you have logged on with your PC correctly and opens up E-Mail send for a while.
As an alternative to this, you can also enter your user name and password for SMTP send.
To do this, start Outlook Express and open the menu Extras - Accounts.
Then select the desired mail account by clicking on its name and then click on Properties.
In the window that opens, click on Server first, then on My server requires authentication.
Generally, this should do the trick: Now, when sending an E-Mail, the user name and password you usually use to log on will be sent to the SMTP server.
If you need other information for your logon, click on Settings first and then activate Log on using.
Then enter the account name and password that you need to log on for SMTP send.
