A public folder added to "favorits" does not show subfolders within Outlook.
I have a real strange issue which seem to be a general problem because I can replicate this on multiple systems with different Exchange servers and different version of Outlook.
I have a public folder called SALE. I have created multiple subfolders.
I browse to this Public Folder, right click and choose add to favorits. I choose properties and check that I want to see subfolder + later created sub folders. Then I go to the "favorits" right click and chose "Show in Favorits" to make the Public Folder visible in the upper left corner of Outlook under FAVORITS.
The problem is, that even though I checked the "Show sub-folders" no sub-folders is visible within favorits.
The Server is an Exchange 2010 but I have seen this issue also with Exchange 2013.
