iTunes cannot sync mail
When I try to sync mail in iTunes the checkbox is not clickable and no mail accounts are shown.
Tried:
plugging in a different iphone (update OK)
updating software
reinstalling software
creating a new account
(the problem resides on the mac)
deleting caches
Deleting mail accounts, caches and preferences
deleting iTunes library, caches and preferences
Nothing! Just the same error.
Can anyone help me?
MacBook Air, Mac OS X (10.7.3), Smaller is better!
