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:

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 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.

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.

Incorrect mail server settings can prevent Outlook from connecting to the mail server. Check and verify your email settings following these guides:

• Check IMAP email settings in Outlook
• Check POP3 email settings in Outlook

Ensure that your login credentials are correct. First, check if you can log in to your webmail using the current password. If you are able to access webmail, update the password in Outlook to match the one used for webmail.

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.

Sometimes, a simple restart can resolve temporary glitches. If restarting Outlook doesn't help, try restarting your computer.

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 Outdated software can sometimes cause compatibility issues.

A corrupted Outlook data file (.pst or .ost) can cause the 0x800CCC0D error. You can utilize Outlook's built-in Inbox Repair Tool to scan and repair corrupted data files. Find out more and follow the steps at the Microsoft Guide.
