Hi @AlbertLlaguno-0244
You most definitely can share a file from a business account with OneDrive or SharePoint to a personal account.
It is important to know how your business (Microsoft 365) tenant is setup, so if you aren't the Administrator, I would reach out to them and ask how the permissions are set up. They must be set up to allow sharing to external users (see documentation below).
