Fixing Outlook After Switching Internet Service Providers

Typically when you switch Internet Service Providers (ISPs) there is little to do aside from replacing a modem and sending your money to a different place. However, there can also be an unfortunate side effect that prevents you from sending email through Microsoft Outlook 2010. This occurs because your new ISP is blocking a specific port (port 25) used by Outlook to send mail through your account. Fortunately you can configure Outlook to use a different port instead and resume normal program operation.

 

Step 1: Launch Outlook.

 

Step 2: Click the “File” tab at the top-left corner of the window, click “Account Settings,” then click “Account Settings” again.

File, Account Settings, Account Settings

 

Step 3:  Click your account, then click the “Change” button.

Click your account, then click Change

 

Step 4: Click the “More Settings” button at the bottom-right corner of the window.

Click More Settings

 

Step 5:  Click the “Advanced” tab at the top of the window, click inside the “Outgoing Server” field, then change the value to “587.”

Click the Advanced tab, then change to port 587

 

Step 6: Click the “OK” button, then click “Next” and Finish to apply your changes.
