====== Troubleshooting 0x800CCC0D error on Outlook ======

The 0x800CCC0D error in Microsoft Outlook typically means that the program is unable to connect to the mail server. This can occur due to various reasons such as network issues, incorrect server settings, or security software interference.

The typical error message for the 0x800CCC0D error in Microsoft Outlook looks something like this:\\ 
  (0x800CCC0D): 'Cannot find the email server. Verify the server information in your account properties.'

To troubleshoot this error:

===== 1. Check Internet Connection =====
To resolve the 0x800CCC0D error, start by ensuring your internet connection is working properly.

First, open a web browser and try accessing a website to confirm that your connection is active.\\ 
You can also try accessing your email account via [[https://lookafter.com/login|webmail]].

If you cannot access websites or webmail, try restarting your Internet router. Turn it off, wait for about 30 seconds, then turn it back on. This can resolve temporary network issues.

If the issue persists after restarting the router, contact your internet service provider (ISP) for assistance.

===== 2. Check Firewall and Antivirus =====
Firewalls and antivirus programs are designed to protect your system, but they can sometimes mistakenly block legitimate connections, including those needed by Outlook to connect to the mail server. This can lead to the 0x800CCC0D error.

**Temporarily disable your firewall and antivirus software** to determine if they are causing the issue. This can help identify whether these security tools are blocking Outlook's connection.

If you cannot log in with the current password, contact your avomaster or voadmin to reset or change your password. Once updated, make sure to reflect these changes in Outlook.

===== 5. Restart Outlook and Your Computer =====
Sometimes, a simple restart can resolve temporary glitches. If restarting Outlook doesn't help, try restarting your computer.

===== 6. Update Outlook =====
Ensure that you have the latest version of Outlook installed. Outdated software can sometimes cause compatibility issues.
