SYMPTOMS

In Microsoft Office Outlook 2007, the BeforeFolderMove or the BeforeItemMove event is not called by a custom application after a while.

For example, there is a custom application which you can run to create a new folder that contains several subfolders for Office Outlook 2007. The application calls the BeforeFolderMove event, in which the cancel property is set to true to prevent users from moving folders. When you run the application and then try to move the folders, they cannot be moved. However, after several tries, you can move the folders.
