Answer 1

Hello

Is this regarding a third party email in Outlook Classic? If so, it is a known issue.

Many users seem to have this issue recently. Microsoft is still investigating this issue. The current workaround is published here: https://support.microsoft.com/office/users-get-errors-0x800ccc0e-0x800ccc0f-synchronizing-gmail-and-yahoo-accounts-in-classic-outlook-e5a7b684-7c5c-4848-ab2d-d48291451f67

Answer 2

Error 0x800CCC0E is one of the classic Outlook send/receive errors listed for connection problems.

Use these steps that apply to classic Outlook on Windows:

1. Confirm password and account

• If the email account password was recently changed on the provider’s website, update it in Outlook as well.
• For classic Outlook, follow the guidance under Have you changed your password recently? and, if needed, see Reset a forgotten Microsoft account password.

2. Check for account/app‑password issues

• If Outlook shows a message like “Please create an app password for Outlook on your email provider's site”, go to the email provider’s site, generate an app password, then paste that into Outlook when prompted.
• For more details on adding or reconfiguring the account, see Add an email account to Outlook for Windows.

3. Start Outlook in Safe Mode

• Some add-ins can block send/receive.
• Press the Windows key, type: outlook.exe /safe and press Enter.
• If send/receive works in Safe Mode, create a new Outlook profile as described in Fix your Outlook email connection by repairing your profile or Create an Outlook profile.

4. Repair the Outlook profile

• A damaged profile can cause 0x800CCC0E and other connection errors.
• Use the steps in Fix your Outlook email connection by repairing your profile to repair or recreate the mail profile, then test send/receive again.

5. Repair the Outlook program

• If the application itself is damaged, run an Office repair using the steps in Repair an Office application.

6. Repair Outlook data files

• If Outlook uses a .pst file, run the Inbox Repair Tool (ScanPST) as described under Run the Inbox Repair Tool / Repair your Outlook personal folders file (.pst), then restart Outlook and test send/receive.

7. Check antivirus email scanning

• Some antivirus products scan email and can block connections after detecting a problem.
• Contact the antivirus vendor’s help desk or temporarily disable email scanning (not the entire antivirus) according to their guidance, then test send/receive.

If using Outlook.com in a browser and not the desktop client, also verify:

• Cloud storage is not full; if it is, free space using the mailbox storage page.
• The account is not blocked due to unusual sign-in activity; if blocked, follow unblock my Outlook.com account.

If none of these steps resolve the issue, collect the exact text of the error, confirm whether it occurs for all accounts or only one, and then use Outlook’s in-product Help → Still need help → Chat with a support agent to reach Outlook support again with these details.
