"System.NullReferenceException" error on startup


The following error may appear in a dialog box when Outlook 2010 starts up:

System.NullReferenceException: Object reference not set to an instance of an object.
   at CdsAddin.CdsClient.PartialUrlEncode(String toEncode)
   at CdsAddin.CdsClient.GetSpamHandlingInfo(String profile, String storeEid, Boolean createSpamFolder, String reason)
   at CdsAddin.CloudmarkAddin.SetSpamFolderIcon()
   at CdsAddin.CloudmarkAddin.ThisAddIn_Startup(Object sender, EventArgs e)

Close this dialog box to continue launching Outlook 2010.  DesktopOne functions normally.


This error may appear when one of these third-party plugins is installed on the same computer as DesktopOne:

  • gSyncit
  • CompanionLink

Check for these plugins on your computer and disable them to eliminate the error.  If none of these plugins are installed on your computer, contact Support for further assistance.
