Click OK. You will come to the following screen. Locate the public folder where the deletes occurred, go to the “Items” Tab and at the bottom of the screen select the “Deleted Contents” radio button
If there are any deleted items in the Public folder you select it will look like this. Select the item, right click it and choose “recover items” The folder re-appeared immediately via our Outlook clients
