Is there a way I can get assignee email address from the issue details or user details?
rest/api/2/issue/issue-6659
rest/api/2/user/search?username=user1
I have been reading about the public visibility of the contact email address.

- Does everyone should set their email visibility to Anyone to get mail address from issue/user details?.
- If yes, is there a way where admin can update all the users mail visibility to Anyone by api or some other way?
