Sometimes Outlook users get the 0x800CCCDD error ('Your IMAP server closed the connection') whenever they send or receive #emails via an IMAP account. This particular error code is signaling that the Send/Receive feature has failed.

1. Click Outlook 2010's "File" tab.

2. Double-click an email account's name in the list to edit its settings.

3. Click the "Advanced" tab on the settings window, then locate the Server Timeouts section.

4. Click "OK" and then "Cancel" to save the new timeout setting for the selected account.
