According to SimpleToRemember.com (also known as Judaism online), prophecy is only possible if the majority of the Jewish people are living in Israel:
Prophecy can only exist in Israel when the land is inhabited by a majority of world Jewry. During the time of Ezra (circa 300 BCE), when the majority of Jews refused to move from Babylon to Israel, prophecy ended upon the death of the last prophets—Haggai, Zechariah and Malachi.
Is this the widespread opinion on the subject? What is the scriptural basis for this idea? Does this mean that prophecy was impossible during the Babylonian Captivity?
