Hi all, I need to be able to add a new custom field to a IPM.Task mail item within my OnSyncSave event sink. I need to be able to access the field later from the UserProperties collection of the Taskitem class within Outlook. I can modify currently existing properties without trouble but I dont know how create a new property properly. For info, I cannot force the user to use a specific form when creating a task so cannot rely on being able create the property before submission to the server Any help would be greatly appreciated!!
