How to Get Outlook to Send Email via SMTP After a 530 Error

Microsoft Outlook 2007 Error 530 occur when you use a laptop on a network that is not your own. You can receive emails, but you cannot send them. Some wireless Internet service providers block Port 25 because they think you are a spammer sending malicious emails. Here are a few tips to get around Error 530.

Instructions

1. Open Microsoft Outlook. In the "Tools" menu, navigate to "Accounts," "Server" and then "Advanced." Observe the SMTP port setting. If it says "25," change it to "587." Press "Apply," and then click "OK." Exit Outlook, restart your computer and reopen Outlook. Send an email to ensure that your email goes through the system.

2. Attempt an alternative solution. Inside Outlook, select the "Tools" menu, click "Account Settings" and "More Settings." Check the "My outgoing server (SMTP) requires authentication" option. Exit Outlook, restart your computer and reopen Outlook. Send an email to see if your email goes through the system.

3. Consider temporarily using web-based email instead of Outlook. For example, if you have a Yahoo! email address and normally access your email through Outlook, open a web browser and type "http://mail.yahoo.com" instead. Check with your specific email provider to see if webmail is available and what address to use.

Tips & Warnings

• If changing the port from 25 to 587 works for you on the road, you may need to change your port back to 25 when you use your laptop at home.
