How to re-order accounts in Mail.app (El Capitan) Since I upgraded to El Capitan the Mail.app was upgraded also (to version 9.2) and the ability to re-order accounts was disappeared.
Now I cannot move accounts in the preferences.


Who knows is there any configuration plist to resolve this issue manually?
If you delete the accounts from Mail.app and then add them back in the order you want them to be in, it will save the order. There is currently no way to manually change the order after the accounts have been created within Mail.
