Reader Question:
“Hi Wally, How to fix error 0x800CCC18 in the Windows live mail. Microsoft edge. Thank you.” – Vitor Oliveira., Brazil

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

An update by Microsoft seems to have enabled Secure Password Authentication on a lot of Email clients including various versions of Outlook Express and Windows Live Mail. This seems to have caused some temporary issues like the 0x800CCC18 error.


Here are some ways to fix the 0x800CCC18 error in Windows Live Mail.

Disable Secure Password Authentication To Fix The 0x800CCC18 Error 

As explained under the previous heading. The Secure Password Authentication feature in Windows Live Mail (and Outlook) seems to be the cause of this issue. Since this is a corporate feature, it can cause issues on many computers that don’t make use of it. Therefore, disabling this feature should fix the problem.

Open Windows Live Mail and click Tools as shown below. After that, click Accounts.

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.
