amazing works!
Thank you so much for your post, it makes more directly when controlling the outlook.
May I ask how I can create a "normal" folder by "_OL_FolderCreate".
https://msdn.microsoft.com/en-us/library/microsoft.office.interop.outlook.oldefaultfolders.aspx
from the above outlook "OlDefaultFolders enumeration", where all are functional folder but not found a usual folder?
