If the issue is simply that you cannot remember the email address, start here:
https://account.live.com/username/recover
But... here's more info on "old" accounts...
1. The Account Recovery form is the only way to recover an "old" account.
2. A common problem with "old" accounts...
If you have, at any point, gone for a year without signing in to the account
it was closed and can't be recovered.
3. Many people ask about contacting a Support Agent, but in this article https://support.microsoft.com/en-us/account-billing/contacting-support-for-a-microsoft-account-bb65aa6a-9135-31df-0b36-d6318d6f4e0f
is the warning that
* To protect your account and its contents, our support agents and advocates are not allowed to send password reset links or access and change account details.
* They cannot do more than you can do for yourself with the forms available from the website.
