Issue: Hi guys! Could you please help me to resolve the issue that keeps me from sending e-mail messages via Outlook.

Nothing else happens, the system neither freezes nor crashes and there are no other errors appearing, no BSOD, nothing. The problem is that Outlook does not work, which is a serious problem for me because I manage my work and my personal emails. Please help.

Solved Answer

Microsoft Outlook Error Code 0x80042109 is the issue that appears while sending messages via Outlook. Outgoing emails cannot reach the receiver and the message with information about email server issues get on the screen.[1] The issue seems to be important and related to changes of some sort but the user, in most cases, didn't interfere with anything.

While some of Windows errors are accompanied by system slowdowns, crashes, freezes, and similar issues, the others show up as if out of nowhere.[2] System errors are typically expressed in the form of BSOD windows or pop-up notifications, while software-related errors emerge when trying to exploit a particular application, such as Microsoft Outlook.

Several users have reported that when they attempt to perform any actions with Microsoft Outlook, the following message emerge:

“Sending reported error (0x80042109): Outlook cannot connect to your outgoing (SMTP) e-mail server”


“Sending and Receiving reported error (0x80042109): Outlook is unable to connect to your outgoing (SMTP) e-mail server.”

If you have received the notification Nr 1, it means that your e-mail messages cannot be sent due to Internet connectivity issue. The second message indicates the fact that Outlook has become irresponsive, which is why it can’t be installed, opened, updated, configured, etc. So, naturally, you will not be allowed to send or receive emails. Specialists notify that Outlook error code 0x80042109 may be triggered by the corrupted temporary Internet files or virus/malware infection.
