I tried to search if someone has asked this question. The closely related to this I found here, but I am not sure that it is correct to my question beside the person who asked that question didn't accept any answer.
Suppose Jennifer Boyle is a married woman and her husband is Peter Smith. This woman is an ambassador of one country assigned to our country. She is introduced here as Jennifer Boyle. As an ambassador, however, I have to respect her especially when I speak to her in a formal situation, such in an audience (especially when I asked her about her country's policy).
Then my questions are:
- What is the proper way to address her? Should I call her Madam Jennifer? Madam Boyle? Madam Smith? Ms. Jennifer? Ms. Boyle? Mrs. Jennifer? Mrs. Boyle? Mrs. Smith? Or what?
- When I have to address her with HER POSITION as an ambassador, how do I address her? Madam Ambassador? Mrs. Ambassador? Ms. Ambassador? Or any other?
