Outlook Error 0x800CCC0B
Error 0x800CCC0B in Microsoft Outlook typically indicates a server or connection problem that is preventing Outlook from completing the send or receive operation. Here is how to resolve it.
Step 1: Restart Your Computer
This error can be caused by a stuck Outlook process or a temporary network glitch. A restart clears both and resolves the issue in many cases.
Step 2: Remove and Re-add the Mail Account
If the error continues after restarting, try removing the email account from Outlook and setting it up again:
- In Outlook, go to File > Account Settings > Account Settings
- Select the affected email account and click Remove
- Close and reopen Outlook
- Add the account again with the correct settings
