How to Determine the SMTP Server in Outlook

by Jason Artman

When you send messages using the Microsoft Outlook email client, your computer most likely connects to a server using the Simple Mail Transfer Protocol, or SMTP. Your Internet Service Provider or email company provides access to this server, which relays your messages to their final destinations. If the address of your SMTP server is configured incorrectly, you may be able to receive messages, but not to send them. If you contact technical support regarding this issue, you will need to provide the address of your SMTP server. In Microsoft Outlook, you can obtain this information with a few clicks.

Outlook 2010

Click the orange "File" button at the top of the window.

Click the "Account Settings" button, then click "Account Settings" on the menu that appears below.

Click the email address that you want to determine the SMTP server for, then click the "Change" button.

Examine the information shown in the "Outgoing Mail Server (SMTP)" field to determine your current SMTP server.

Outlook 2007 and 2003

Click the "Tools" menu at the top of the window.

Click "Account Settings" in Outlook 2007 or "E-mail Accounts" in Outlook 2003.

Click "View or change existing e-mail accounts" and "Next" in Outlook 2003. If you are using Outlook 2007, skip this step.

Click the email account that you want to view the current SMTP server for, then click the "Change" button.

Examine the information shown in the "Outgoing Mail Server (SMTP)" field to determine your current SMTP server.
