This article will show you how to fix error 0x800cccdd in the computer version of Microsoft Outlook. Typically, error 0x800cccdd occurs when Send / Receive is enabled on the IMAP server for Outlook.

Steps

1. 1 Understand what is causing the error. Error 0x800cccdd appears along with the message "The IMAP server has closed the connection" - this means that the "Send and receive" function, which synchronizes emails with Outlook when connected to the Internet, did not work. This is not really a problem because the Send / Receive feature is not designed to work with IMAP servers — such servers can sync content without the need for Outlook settings.
   • Since the error is a result of a failure in the Send / Receive function, to fix this error, you just need to disable the specified function (the error may still appear when you start Outlook, but not while using Outlook).
2. 2 Start Outlook. Double click on the Outlook icon on your desktop; it looks like a white "O" on a dark blue background.
   • If you haven't logged in to Outlook yet, please do so with your email address and password.
3. 3 Click on the tab Sending and receiving. It's in the upper-left side of the Outlook window. The toolbar will open (at the top of the window).
4. 4 Click on Send and receive groups. It's in the Send and Receive section of the toolbar. A menu will open.
5. 5 Click on Define send and receive groups. It's an option at the bottom of the menu. A pop-up window will open.
6. 6 Uncheck the box next to Automatically send and receive mail every. It's in the All Accounts section below the bar in the middle of the pop-up.
   • Also uncheck the box next to "Send and receive mail every automatically" in the "When Outlook is turned off" section.
7. 7 Click on Close. It's an option at the bottom of the popup. The settings will be saved.
8. 8 Restart Outlook. Close Outlook and then start it and allow mail to sync. The error will no longer appear.

Tips

• In some cases, the 0x800cccdd error appears when the computer disconnects from the Internet during the synchronization of letters.

Warnings

• Disabling the Send / Receive function for a POP server may result in emails not being synchronized. Disable this feature only if you are using Outlook with IMAP.
