How to get your YouTube account or Hotmail / Outlook account back?

Unfortunately i have a problem and not much hope but i will give it a try.

I used to have a YouTube account on which I uploaded videos. That was back when there was no "Outlook" but "Hotmail". In 2015 I uploaded a video for the last time.

My laptop at the time gave up the ghost and I had to go through a lot in my private life, which is why I didn't care much about it.

After a few months I wanted to log in again but then there was no longer "Hotmail" but "Outlook". At my age at that time, I didn't take all of this seriously with the details of my data. I just entered an abbreviation or any date of birth.

I've been trying for years now. Unfortunately, I no longer know my YouTube password. Just the mail. However, I don't know the password for the mail either. I wrote down some passwords and emails, but I can't get in anywhere because I gave incomplete information at the time.

Whenever I try it on YouTube, I want to send an email to my email address to reset my password. But since I can't get in there because I don't have the password there either, I can't get any further. I also had a different cell phone number at the time. So you can't send an SMS either.

I know it sounds impossible, but I really care. Perhaps does any of you have an idea or even the same problem?

Sounds a lot like the account is gone, but maybe write / call the customer service of Youtube?

Have already looked. They don't have a seat here. Can't call anyone.

Many Thanks.
