The Outlook 0x80042109 error usually appears when a user tries to send an e-mail. In such scenarios, the email does not move outward and Microsoft Outlook begins to display an error message on the screen.

Experts point out that the 0x80042109 Outlook error code can be caused by corrupted temporary Internet files or infection by viruses/malware.

Error message: Task ‘SMTP server name – Sending and Receiving’ reported error (0x80042109): ‘Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact the server administrator or Internet service provider (ISP).

Disable antivirus software

In addition, you should also try to disable your antivirus to fix the error 0x80042109. It is no secret that antimalware programs often conflict with other programs installed on the system.
