old xbox 360 account on my xbox one

The problem is that I never linked my xbox 360 to my xbox live account, [...]. So I'm trying to link my xbox live account to my xbox 360, but all I get are error messages.

My account is linked to my xbox one without any problems, but in order to save xbox 360 game data on my xbox one, I have to download my/a xbox 360 profile, which I can't do because my profile won't connect to xbox live.

The problem is, since you used a Xbox One, your Microsoft Account is now already "occupied" with a Gamertag, so you can't use that Microsoft Account to bring your old Xbox 360 offline Gamertag online.

You COULD create a new Microsoft Account to bring your Xbox 360 account online, but you won't be able to access the savegames with your Xbox One account, as Savegames can't be transferred between accounts.

So depending on how much you already invested in your Xbox One account, you might try to bring your old Xbox 360 account online, and use that on your Xbox One, and start your Xbox One gaming history over, or you can abandon your Xbox 360 saves and just use
your old account on the Xbox One to download your previous Xbox 360 digital games, and start these over with your new Xbox One account.

Since it's not possible to merge Gamertag accounts, you will have to decide which account you wish continue to use for actual gaming, and which account you simply keep to claim license ownership for downloaded games.

the xbox one account is also the xbox 360 account, they are the same

just sign into the xbox 360 with the same account as your xbox one.

your old xbox 360 account will most likely be attached to an older email account, nothing can be transferred.

Hi, I do have xbox live on my xbox one s account but I don't on my old xbox 360 accounts as I don't use them anymore.

If you follow the instructions on here
support.xbox.com/.../sign-in-to-another-console then you can log into your old xbox 360 account on your xbox one. As for playing the old xbox 360 games, check this site for the full list of xbox 360 games that will play on an xbox one

I see, thank you. Would it be possible to access my account from any Xbox 360, even if it’s not my old one?
