Hi,
Did you want to use the same Microsoft account in different PCs with OneDrive and the same account will not share OneDrive sync files and folders under different PCs?
It's impossible, OneDrive cannot use the same account to sync different contents on different PCs. It is recommended that you use different personal accounts to synchronize your data.
