Hi Garima,
It is a disaster the implementation made with OneDrive for users who have a personal account and a business account.
In Android it gives 1208500 synchronization error and there is no way to make it work.
In the desktop version, when you disconnect and try to connect with OneDrive again, it takes you directly to identify yourself with OneDrive for Business account and there is no way to choose the personal account, so you cannot synchronize on the PC either.
I had to get a Box account to be able to synchronize my devices.
As I said, a disaster.
:-(
