Because you’re all wise people here: anyone had any success recovering a YouTube channel that was registered to an email address you no longer have access to?
I keep trying via the Google Account Recovery but end up at the same dead end all the time.
You may be able to use a back door through brand management and add an account manager to the youtube account, thus changing the email on file. I don’t fully understand it and I don’t even personally have a youtube account, but it’s done through google services as I remembered podcastage talking about it.
Long story short, he lost access to his large account over a suspension of his small personal account and the two were somehow linked. This is him on another of his secondary channels mostly whining about the situation as a whole, I tried to timestamp the relevant portion of the video but the resolution is presented amidst a lot of complaining so you’ll have to determine whether or not this is useful to you.
Also, I don’t know which google services you still have access to but at least it’s an angle you can investigate and it may be contingent on whether or not your channel is monetized, that part I cannot say.
Thanks for the info.
My case is much simpler. I had a YouTube channel that was registered with an email I no longer have access to. No ban, no monetisation issue just bad admin 
All red tape and unrelated plot points aside, may be worth investigation as to whether one can change the email on file by registering a new owner/manager for their channel.
I may be missing a subtley but wouldn’t that require you already have access to the channel? That’s what I don’t have.
The other guy was banned from the 400 subscriber account, the login of which he used to access his 250,000 subscriber account which was unaffected by the corrective action aside from him not being able to access it. He had no access to his channel.
He went through something with google services to shift ownership of the channel which is how he changed the email on file and gained access before youtube ultimately reversed their decision about the ban.
I only mentioned monetization because I don’t know if youtube considers that only a monetized channel is eligible for brand management but these days who even knows what constitutes a brand, it’s all just a bunch of jargon used by people who enjoy to jarg on.
