I've set up phabricator and added several users. I noticed that I can change a user's real name or username, but I am unable to change their email address. Is there some reason why this is not exposed to admins? Is there a server setting that allows admins to change email addresses.
It might be new, but they have a way now. I'll just list it here in case anyone has the same question later.
Log in to the server, where you have your Phabricator install, and use ./bin/accountadmin. That will let you change or add accounts at will. If you just want to look at the user, you can look in the phabricator_user database and check the user table or the user_profile table.
