Issue: How to Fix Windows Live Mail Error Code 0x800CCC90?

Hi guys. For some reason, the messages in my Live Mail account don’t get sent out. The all accumulate in the Outbox and stays there for a week or more. I keep receiving a pop-up message that Windows Live Mail is unable to send or receive messages for the particular email address account. The server error 0x800CCC90 is mentioned. This happens with all email addresses that I try to contact to. What should I do?

Solved Answer

Windows Live Mail is the latest free desktop email app developed and owned by Microsoft. Earlier, the app was known as Outlook. Windows Live Mail is used by millions of mail users and praised for being clear and simple. For now, it comes as a part of Windows Essentials suite along with Live Write, MovieMaker, OneDrive, and Photo Gallery apps.  Although this email app does not stand among the most problematic Windows apps, it causes some minor inconveniences to people from time to time. Recently, we stumbled upon several reports where people express their frustration regarding Windows Live Mail Error 0x800CCC90. The full error message reads as follows:

Unable to send or receive messages for the *** Email address is removed for privacy *** account. An incorrect password was entered. The next time you send or receive messages, you’ll be asked to enter your user name and password for this account.

Server Error: 0x800CCC90
Server Response: -ERR Auth-Status: Invalid login or password
Server: ‘pop.rcn.com’
Windows Live Mail Error ID: 0x800CCC92
Protocol: POP3
Port: 110
Secure(SSL): No
Server Error: 0x800CCC90  Server Response: -ERR Auth-Status: Invalid login or password

If this message shows up on the screen, it means that none of the email messages from a malfunctioning WLM account are sent to the recipients. They are sent to the Outbox folder and left there for an unspecified period of time. According to people’s reports, the 0x800CCC90 error may be triggered by Avast or another third-party anti-virus. Besides, the corrupted data within the WLM app or the outdated app itself may be the culprit of the server error 0x800CCC90. To fix that, please try the following steps:
