How to fix Outlook error 0x8004060c

By restarting your computer, you will restart all the programs and processes that were running on it in the background, which have prevented Outlook from sending and receiving emails, and caused error 0x8004060c to occur.

Turn off your computer on the power (on/off) button, and turn it back on after a few minutes. Additional options you can consider is unplugging the computer from the power cord, or removing its battery (if you use a laptop whose battery can be removed).

The router is the in-door "plumbing" system for Internet connection. If one of its "pipes" is stuck, Internet won't run through it. Maybe the router itself is the reason behind error code 0x8004060c and doesn't let you send or receive emails, as it doesn't share the Internet connection as expected. Maybe it failed to reconnect, after your Internet connection being down, or maybe it just got stuck randomly.

Restarting the router is the simplest way to regain Internet access and fix this error. Unplug the router from the power strip, and then plug it back in after a couple of minutes.

Note: If you use a modem, make sure to restart it, as well.

For Outlook to send and receive emails and attachments properly, it needs a strong and reliable Internet connection. If the connection is not stable, then this Outlook error can occur. One way to fix this issue is to improve the strength of your Internet connection. 

What you may try is the following:

• If your computer is far away from a router, get the router closer to the computer;
• Buy a stronger router, with a greater Wi-Fi range;
• Connect your computer directly to the router, using an Ethernet cable;
• Switch to a better Internet plan.
