OneDrive personal and OneDrive for Business are completly different and you can´t share folders between these accounts.

You can only generate a link, but you will never see your shared folders in your OneDrive personal account or in your OneDrive for Business account.

Just use only OneDrive for Business or only OneDrive personal otherwise it is not working.

My advise: use a professional cloud storage Service.
