Hello
For each Windows user profile, you can only run one OneDrive instance with personal account, but you can run more than one OneDrive instance with work/school account.
So that means, if you want to add another OneDrive instance for a different personal account, other than the one you use to log in, it is not possible.
However, would you consider changing the email address associated with your computer's current admin account? If so, then you will get to use the one with the subscription.
To do so, Go to Settings > Accounts > Your info
Click on Sign in with local user instead. follow the steps and finish the rest.
(If you don't see the "sign in with a local account instead option, click on "Stop signing into Microsoft apps automatically" first, then relaunch this page. )
Restart the computer (Do Not skip)
Go to Settings > Accounts > Your info
Click on Sign in with Microsoft account instead. follow the steps and finish the rest. This time sign into the account that carries the subscription.
Restart the computer (Do Not skip)
