There is a distinction between personal onedrive accounts and 'business' onedrive accounts that you get from work/university/organization.

Because microsoft changed their sync client not too long ago, users sometimes run into this problem when trying to log in with a business account. For example, when I had to get the sync client setup on my personal PC, I had to use the troubleshooting info in these articles to be able to log in successfully. This should give you enough info about the issue, if you don't already know.
