A possessive pronoun can be used as a direct object and as an indirect object. It can never be used as an object of preposition. Take the following sentence for example: She gifted her daughter a car. Her is a possessive pronoun, and her daughter is the indirect object of the verb gifted. Another example: He ate his breakfast quickly. He is the possessive pronoun, and his breakfast is the direct object of the verb ate.
