The pop-up page shows you two sections: One for specifying the details of the folder, the other for specifying the access rights to the folder.
The section to specify the details of the folder:
You can give your new public folder a name, in this case “Company Mail” and it also lets you choose the type of folder to create, in this case a Mail folder. If you have nested folders you can also choose which one this new folder should be underneath, by selecting the relevant folder from the Parent drop down list.
The section to specify the access rights to this folder:
In this example, we have selected four users and given two of them Read/Create permissions, and two of them Read/Create/Edit permissions. Press OK to complete the task.
