I am the Communications Manager of an NGO and I would like to delete this YouTube Channel that was created by a former employee: https://www.youtube.com/user/wilpfgeneva
I do not know which email address was used to create that account and I have already tried all possible email recovery solutions.
The account is not associated to Google+ so I cannot send a message on YouTube.
How can I find out which email address was used to open such channel? Is there anything similar to Google "site share request"http://sitesguide.pjrprojects.co.uk/google-sites/how-tos/user-access-assist?
That is how I managed to get access to an old website (again created by a former employee), which I need to close down.
