Answer

PROBLEM

Public folder scanning fails and does not create the GFI MailEssentials Public Folders.
 
You may see the following errors in ..\MailEssentials\Antispam\DebugLogs\PFTrainEWS.log:
 
error  ","PFTrainEWS","error:The request failed schema validation: The element 'ParentFolderId' in namespace 'http://schemas.microsoft.com/exchange/services/2006/messages' has incomplete content. List of possible elements expected: 'FolderId, DistinguishedFolderId' in namespace 'http://schemas.microsoft.com/exchange/services/2006/types'."

"error  ","PFTrainEWS","error:Failed to GetFolderObject reference not set to an instance of an object."

ENVIRONMENT

  • GFI MailEssentials 
  • Microsoft Exchange 2013

SOLUTION

  1. Verify that CU3 is installed
    1. Open the Exchange Management Shell
    2. Type: Get-ExchangeServer | fl name,edition,admindisplayversion
    3. Verify that version is 15.0 and build is 775.38 (Further info could be found here: http://technet.microsoft.com/en-us/library/hh135098(v=exchg.150).aspx)
  2. Verify that the user being used to access public folders has full permissions
    1. Open the Exchange Admin Center
    2. Click Public Folders
    3. Click ... and click Root permissions
    4. Add the user to be used for public folder scanning here and give full permissions

CAUSE

Insufficient privileges for the user performing public folder scanning or Exchange is missing a critical update.
