How to Solve Outlook Pop3 Error? | SmartPCFixer Official Blog

Outlook offers convenience of using email for people, but it also causes as much trouble as virus. As it is used to send and receive mails by internet connection, and it has account encryption settings, it sometimes stops working due to many kinds of errors. One of these errors is the pop3 error which is related to account settings and registry.

To resolve this behavior, make sure that you are using the correct account settings for your assigned e-mail servers. You can obtain the server information from your ISP or local area network (LAN) administrator. To confirm the settings for your Internet E-mail account:

Start Outlook.
On the Tools menu, click Accounts.
On the Mail tab, click the name of your e-mail account, and then click Properties.
On the General tab, verify that your e-mail address is correct.
On the Servers tab, check if the e-mail server information is correct for both the incoming mail (POP3) and outgoing mail (SMTP) servers. Verify that both servers have the correct settings for your password and account name. (You can check your email server information of Pop3 address on internet) Ask your ISP if your server requires you to log on by using a secure password authentication and if your outgoing mail server requires authentication.
On the Connection tab, confirm that the connection that you use is correct. For example, you may connect through a LAN or through a dial-up connection. Without a valid connection, your e-mail program cannot communicate with the e-mail servers.
On the Advanced tab, verify that your server ports are correct. POP3 servers use port 110 and SMTP servers use port 25. Make sure that these ports are correct. For more information, contact your ISP.
Click OK, and then click Close to save any changes.
