mklink: junction actually doesn't work

Question

I did this from cmd.exe as admin

mklink /J "C:\Users\absolute\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\iPhone DATA\iTunes BACKUP”

and I see confirmation of Junction in cmd and even do

DIR "C:\Users\absolute\AppData\Roaming\Apple Computer\MobileSync"

and see smth like

28.02.2015 10.27 <JUNCTION> Backup ["E:\iPhone DATA\iTunes BACKUP"]

so it should work. But when I try to click on Backup link in File Explorer it brings error Location is not available
