Deleting contacts folder for all users

I'm trying to delete the lync contacts-folder for all users, and have found that search-mailbox-command would be helpfull, but the command does not seem to exist anymore on Exchange 2013 CU2? I am not able to find an alternative command that can help me either. Does anyone have any pointers to how I can get this done? I really need to remove this folder for all users. I am open to other solutions than powershell as well.

Thanks for any help!
