How to fix Outlook error 0x800CCC67
Before you begin, please check your internet connection. Sometimes, we experience outlook errors due to an unstable internet connection. If the internet is working properly, and you are still receiving the error, proceed towards the fixes listed below.
- Disable your antivirus software temporarily.

- Repair .pst file.

After attempting each of these fixes, send a test email to check if the issue is fixed. Now let’s take a closer look at these troubleshooting methods.
1] Disable your antivirus software temporarily
Some antivirus programs can prevent email clients from accessing the SMTP server, which can cause several errors like error code 0x800CCC67. To fix this, try disabling your antivirus software temporarily. If that helps, contact the technical support team of your antivirus vendor and ask them to solve the issue.
2] Configure Windows or your third-party antivirus Firewall
If Port 25 is blocked, you will not be able to send emails using any email client. Therefore, you should check if Port 25 is blocked or not. If you find that port 25 is blocked, you will need to configure your Windows Firewall to unblock it. If you are using a third-party antivirus or firewall, you will need to contact their support in order to find out how to unblock port 25. Once you have unblocked port 25, check to see if you can send emails.
3] Troubleshoot Outlook in Safe Mode
You might be experiencing this error because some of your Outlook add-ins are disabled. You can confirm this by launching Outlook in Safe Mode. In Safe Mode, Outlook will be launched with only the essential add-ins enabled.
To launch Outlook in Safe Mode, take the following steps:
- To launch the Run command box, press the Win + R hotkeys.
- Type outlook.exe /safe into the Run box and click OK.
- After selecting the Outlook profile from the drop-down menu, launch Outlook in Safe Mode.
After starting Outlook in Safe Mode, check whether you can send emails. If you don’t get the Outlook error 0x800CCC67 in Safe Mode, it means that one or more of the disabled add-ins are the problem.
Now that you’re in Safe Mode, go to “File > Options > Add-ins.” In the Manage drop-down menu at the bottom of the right pane, select COM Add-ins and click Go. Make a note of the Add-ins that are enabled in Safe Mode.
Now close Outlook and launch it in normal mode. To do this, simply click on the Start menu, type Outlook, and click on the Outlook desktop app. Alternatively, you can also type outlook.exe in the Run command box. In the normal mode, disable the add-ins one by one and send a test email after disabling each add-in. You need not disable those add-ins that were enabled in the Safe Mode because they are not causing the problem. Once you find the add-in causing the issue, consider removing it.
4] Create a new Outlook profile
If you’re having trouble sending or receiving email, it might be because your Outlook profile is corrupted. Try creating a new Outlook profile and sending a test message. If it goes through, set the new profile as your default.
Follow the steps below:
- Launch Control Panel.
- Click the “View” tab at the top of the window. In the “View by” section, click the “Large icons” option.
- Open Mail and go to the Mail setup window.
- In the mail configuration window, Click on “Show Profiles.”
- Click the “Add” button under the “General” tab.
- Now, click OK after you have entered your new profile name.
- Please provide your name, email address and password in the required fields, then click Next.
- When your account is created successfully, finish.
An IMAP account is created in Outlook by default.
If this works, set your new profile as your default profile. To do this, follow the first 4 steps above. After that, select the newly created profile from the drop-down menu and then select the Always use this profile option. Click Apply and then OK.
5] Repair .pst file
One possible cause of this error is a corrupted Outlook .pst file. The .pst file contains data like email messages, contacts, notes, etc. Therefore, if this file gets corrupted, you will not be able to send or receive email messages.
6] Repair Microsoft Office
If the solutions above don’t work for you, repairing Microsoft Office may help.
