Problem sending receiving email

Question

I receive an error message whenever I try to send/receive email. (0x800CCC0E)

Answer 1

Hi Harold Paul,

Welcome to the Microsoft Q&A forum.

I understand how frustrating it can be to see the 0x800CCC0E message every time you try to send or receive email in Outlook. Thank you for sharing the details.

I see that there is already a Q&A Assist answer in this thread. The information provided there is generally accurate for connection-related send/receive issues in classic Outlook. If you have had a chance to try those steps, could you let me know which ones you have already tested and what the result was?

In addition, I would like to add one important point that may apply to your case. There is a known scenario where classic Outlook can show errors such as 0x800CCC0E or 0x800CCC0F when synchronizing Gmail or Yahoo email accounts, depending on the account type and server configuration.

To help narrow this down, please check the following:

• Confirm whether the affected email account is a personal Gmail or Yahoo account (for example, @gmail.com or @yahoo.com), or a different provider.
• In Outlook, go to File > Account Settings > Account Settings, select the account, and check whether it is set up as POP or IMAP.
• Let me know the email domain you are using, without sharing any full email address.

If your setup matches this scenario, the behavior may be related to the known synchronization issue described here: https://support.microsoft.com/en-us/office/users-get-errors-0x800ccc0e-0x800ccc0f-synchronizing-gmail-and-yahoo-accounts-in-classic-outlook-e5a7b684-7c5c-4848-ab2d-d48291451f67

Once you confirm the account type and provider, it will be easier to suggest the most relevant next steps without repeating unnecessary troubleshooting.

I hope this helps clarify the situation, and I look forward to your update.

Error 0x800CCC0E in classic Outlook is one of the connection errors listed for “I can’t send or receive messages in Outlook.” It indicates Outlook cannot connect to the mail server.

Use these steps to troubleshoot:

1. Check server status and connectivity

• Confirm the internet connection is working (browse a website).
• If this account worked before, the mail server might be offline. Contact the email provider or server administrator to verify the server is available.

2. Verify account settings

• In Outlook, open File → Account Settings → Account Settings….
• Select the problem account and choose Change.
• Confirm the incoming (POP/IMAP) and outgoing (SMTP) server names, ports, and encryption (SSL/TLS) match the values from the email provider.
• Make sure the username and password are correct.

3. Check firewall / network restrictions

• Some ISPs or networks block connections to certain mail ports or servers.
• If using a laptop on different networks, the SMTP server that works in one location may not work in another.
• If a firewall or ISP is blocking the connection, request an alternative SMTP server or port from the provider and update the account’s Outgoing server settings accordingly.

4. Repair the Outlook data file (.pst) For many account types, classic Outlook stores mail in a .pst file. A corrupted .pst can cause send/receive failures.

• Run the Inbox Repair Tool (ScanPST) as described in Repair your Outlook personal folders file (.pst). This typically takes about 15 minutes.
• After repair, restart Outlook and test Send/Receive again.

If the error persists after these steps, provide the exact account type (POP/IMAP/Exchange), server names, and any other error text shown with 0x800CCC0E to narrow down whether it is a server, network, or profile issue.
