I can't comment so this is posted as answer.
You have to analyze the ULS-logs concerning the given correlation ID.
Vardhaman Deshpande has put togehter a great article on this on his blog http://www.vrdmn.com/2014/03/view-tenant-uls-logs-in-sharepoint.html
It's merely based on using the and namespace Microsoft.Online.SharePoint.TenantAdministration and the class TenantLog.
