Hi,
1. Assuming that you're using 2.0.x, login as an admin and go to the admin panel.....
2. Hover your mouse over the "system admin" icon and select "Find users" from the pop-up list.
3. Scroll down to near the bottom of the page and in the section called "Type of users to show" select the "only inactive users" option.
4. Click on "Submit" and you will get a list of currently inactive users.
