Solutions to Resolve the Outlook 0x800CCC67 Error<\/h2>
To effectively address the 0x800ccc67 Microsoft Outlook error, follow these detailed solutions. You may need to adjust or choose the solutions depending on your specific version of Outlook and operating system.<\/p>
1. Check Internet Connection<\/h3>
First, check and verify that your internet is working and stable. For this, open a web browser window and visit Fast.com to check the network speed and reliability. If the network has decent speed and is stable, check whether the mailbox server is available or not. For this, log in to the webmail application of your email provider.<\/p>
In case your network is unstable, has no internet, or low speed, try restarting the router and reconnecting the Ethernet or modem cable in your router and PC (if connected to a wired network). If you’re using Wi-Fi, try resetting the Wi-Fi adapter on your system.<\/p>
2. Manage Attachment Sizes<\/h3>
Most email servers have a limit to the size of attachments that users can send. The moment the limit is exceeded, there is an error where the server returns an output to reject the send command. To avoid the occurrence of this error, you should:<\/p>
- \n
- Make sure the total size of files or attachments while creating the email does not exceed the size set on your or the receiver’s email server before sending emails with attachments.<\/li>\n\n\n\n
- Compress the files into a ZIP folder or share large files through cloud services, like OneDrive and Dropbox.<\/li>\n<\/ul>

- \n
- Start Outlook and go to File<\/strong> > Account<\/strong> Settings<\/strong> > Account<\/strong> Settings<\/strong>.<\/li>\n\n\n\n

- \n
- Open Outlook, go to File > Info > Account Settings,<\/strong> and then select Account Settings<\/strong> from the dropdown.<\/li>\n\n\n\n

- Also, go to More Settings<\/strong> > Outgoing Server<\/strong> and ensure that My outgoing server (SMTP) requires authentication<\/strong> or Require login using Secure Password Authentication (SPA) <\/strong>is checked.

To resolve the issue, you can repair the PST file by following these steps:<\/p>
- \n
- Close Outlook.<\/li>\n\n\n\n
- Press the Windows + R<\/strong> keys, type %programfiles%\/Microsoft Office\/<\/strong> or %programfiles(x86)%\/Microsoft Office\/<\/strong> and press the Enter<\/strong> key.<\/li>\n<\/ul>\n
![\"Press](\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2024\/05\/Open-Run-Command.png\")
<\/figure>\n<\/div>- \n
- Open the Officexx<\/strong> folder or root\/Officexx<\/strong> folder. This may vary based on the Outlook or Windows version installed on your PC.<\/li>\n\n\n\n
- Then, find and launch the SCANPST.EXE<\/a> program. <\/li>\n<\/ul>
\n![\"find](\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2024\/05\/find-and-launch-the-SCANPST.EXE-program.png\")
<\/figure>\n<\/div>- \n
- Click Browse<\/strong> to select the PST file located at %localappdata%\/Microsoft\/Outlook <\/strong>folder or C:\\Users\\YourUserName\\AppData\\Local\\Microsoft\\Outlook<\/strong> folder.<\/li>\n\n\n\n
- Once the PST file is selected, click the Start<\/strong> button.<\/li>\n<\/ul>
\n![\"Once](\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2024\/05\/Once-the-PST-file-is-selected-click-the-Start-button.png\")
<\/figure>\n<\/div>- \n
- The tool scans the PST file thoroughly. If any errors and inconsistencies are found, click the Repair<\/strong> button.<\/li>\n<\/ul>
Note: <\/strong>The repair process may take a while based on the PST file size and corruption level. <\/p>
- \n
- After the repair, start Outlook.<\/li>\n<\/ul>
In case the SCANPST fails to repair the PST file<\/a> or crashes during the repair process, you can use Stellar Repair for Outlook to repair the PST file. This advanced tool, unlike SCANPST, can repair and recover all the mail items from a large (up to 50 GB), damaged, corrupt, or encrypted PST file and save them to a new PST file.
