Does anyone know how to recover deleted contacts in Skype. I was going to manage my Skype group contacts but by mistake deleted all my co-workers from a list. If I re-add them, Skype will send an authorization message to contacts. I have googled a lot but to no avail. I do not have a back-up of users list, but there are some files under application data if required. Can the contact list be retrieved without having to re-add users? Any suggestions would be highly appreciated.
