Microsoft account business and personal only accepting personal password

I am trying to authorise a backup application to access my business onedrive.
WHen signing in to office365 after entering the username I have the option of selecting the personal or business account - the email address is the same but the passwords are different - and it seems to work fine.

When I try to log in at it accepts the email address but then gives no further options and will only accept the personal password and hence will only link to onedrive personal

So, the best thing is to rename your personal account to a different address
