How long remains an email in the archive mailbox? Are there any settings here to change?

Indefinitely. Unless you have configured a retention policy with a Delete action, or the user deletes it manually. By default, no items are deleted automatically, be it in the main mailbox or the archive one, everything is kept indefinitely.
