I need to know immediately how to:

(1)-Turn off and disconnect my Evolution email client WITHOUT losing everything therein (address books, Sent files etc.);

(2)-Transfer my address books to some other email client (for example Q.com) without the ordeal of typing each entry by hand;

(3)-Accomplish this change without the infinite hassle of changing my email address (if indeed this is possible).

Thank you.

(I posted an earlier variant of this question a couple of months ago when Evolution began failing, but the answers I got were useless as they did not acknowledge my abysmal ignorance of all relevant matters.)
