Answer:

Public Folders can either be added in two ways:

Adding a Public Folder (steps):

Once a Public Folder Project has been created, click on the Add button and then click on Quick Add. To only migrate all Public Folders, just enter a slash -- which signifies the root of all Public Folders. Otherwise, when defining the path of the Public Folder, there is no need to add a slash at the beginning of the string: simply enter the folder name followed by a slash and then add sub-folder names. Backslashes are not allowed when defining the Public Folder path. Spaces are allowed in the Public Folder name. The path to the Public Folder must exactly match the path in Exchange for that Public Folder. When in doubt, you can always use the discovery functionality.
