Enable authentication for your SMTP server

Enable authentication for your SMTP server

When this happens, you can configure your outgoing server to use authentication before sending this message. To do this, you must first open your account settings;

  • Outlook 2013 
    File-> Account Settings-> Account Settings…
  • Outlook 2010 
    File-> Account Settings-> Account Settings…
  • Outlook 2007 
    Tools-> Account Settings
  • Outlook 2003 and 2002/XP 
    Tools-> E-mail Accounts…-> button Next

Once you have opened the list of configured accounts; 
Select your mail account-> button Change…-> button More Settings…-> tab Outgoing Server-> select: My outgoing server (SMTP) requires authentication

Note: Some ISPs have configured their SMTP servers to never allow sending messages from another network. In this case you can ask the administrator of the network you are connected to (in our example that would be the administrator of the hotel network) for their SMTP server settings or use the web mail provided by your ISP instead.

That's all.
