Microsoft Outlook Error 0x800ccc0E can show up while working on Microsoft Outlook which is configured with an IMAP account.
A message like the one mentioned below may reflect on the screen:
“‘Checking for new mail in subscribed folders on your_account.com.’ reported error (0x800CCC0E): ‘Microsoft is not able to download the folder (null) for account firstname.lastname@example.org from the IMAP mail Server. Error: Unable to connect to the Server. If it continues receiving the same error message, contact Server administrator or ISP (Internet Service Provider)'”
The reason why Error 0x800ccc0E pops up?
The major reason for getting this error message is an improper port number. In Outlook 2002 and 2003, there is a single checkbox available for enabling encryption for incoming e-mails on IMAP Server. The checkbox needs to be selected if IMAP encryption is needed. There are various port numbers for IMAP encryption or non-encryption. In case, if the encryption has been enabled, but the port number has been entered for non-encryption IMAP port or additionally if encryption has actually been disabled but the port number is incorrectly entered as that of IMAP encryption port; above discussed error will take place.
In Outlook 2007 and 2010, the option for IMAP encryption or non-encrypted/disabled-encryption can be selected from the drop-down list. The options shown here are SSL or TSL. While SSL deals with IMAP Server encryption port, TLS is also referred to as STARTTLS works with IMAP Server disabled-encryption port. In Outlook 2010 if you have entered improper port numbers with matching IMAP Server, instead of the above-mentioned error message it will show the message as either:
“Operation timed out” or “Secure connection to the Server could not be established”
