"Outlook cannot synchronize subscribed folders" with error 0x800CCC0E
Last Updated a year ago

Problem Description

After setting up Outlook to access your mail, it says 3 of 4 tasks have been completed successfully with an error indicating "Synchronizing subscribed folders for email account reported error 0x800CCC0E: 'Outlook cannot synchronize subscribed folders"

This means that Outlook has not been set-up to recognize that the server or profile corruption is due to a windows update that requires an Advanced IMAP configuration parameter put in place to properly read from the folder structure. This is called the IMAP Path Prefix. or the Outlook profile is corrupted

Problem Resolution

To fix this issue:

  1. open your account settings and head to the Advanced tab. At the very bottom of the window, you'll see an option entitled "Root folder path". Set this to INBOX in all capital letters.
  2. Click OK to apply the settings.
  3. You will now need to close Outlook entirely, then re-open the software for the change to take full effect.
  4. You should now find your connection to the server working as normal.


If you find your mail folders have disappeared after making this change, simply revert the change and restart Outlook and your folders will return. You may need to restart your computer as sometimes Outlook doesn't fully close until you do so.
