In a letter to a Caribbean ambassador, the appropriate salutation is "Your Excellency." This formal greeting acknowledges the ambassador's diplomatic rank and position. Following the salutation, it is customary to address the ambassador by their title and last name, for example, "Your Excellency, Ambassador Smith."
The proper title for a retired ambassador is "Ambassador (Ret.)"
The salutation for a retired General is "General". A retired general can also be addressed in a letter thus: General W. Smith (ret):
Dear Mrs Ambassador..
An ex-ambassador is often referred to as a former ambassador or a retired ambassador.
His honor or Your honor is the proper salutation for a retired judge. The use of the word judge in title and introductions is not used after retirement.
His Excellency, Ambassador of ................... This salutation can be used when writing to the Forein ambassadors of all countries.
Salutation for a current Ambassador is His or Her Excellency. Also Ambassador and last name of and country. I believe that since former military and President and Senators etc.....retain their title....Like President Carter.....and military usually has Ret. after the last name I think as a salutation on an Envelope it would be His Excellany John A. Gavin, Ret.
The Salutation itself would not actually change once the officer has retired, it would still be rank, and name, such as 'Chief smith'.
On the Envelope His/Her Excellency Mr./Ms./Dr./Rev. [name] Ambassador (or High Commissioner) of [country in full] In letter Dear Mr/Mrs Ambassador
You would address a retired Rear Admiral as "Rear Admiral (Retired) [Full Name]" on the envelope and in the salutation of the letter.
No, she retired from that career in 1992.
