I have a user that whenever she tries to open mail preferences it consistently locks up with the pinwheel icon and requires her to force quit mail. Mac mail was fine until a gmail account was added to her list of accounts.
Aside from the prefs issue, Mac mail runs fine. She has 10.8.2 installed. When she called Apple, they suggested reinstalling the OS by using the recover option at bootup.
Is there a trick we can do at the terminal, finder or elsewhere to fix mail? The same issue exists in safe boot.
Does mail have a way to easily reset preferences while retaining the accounts configured and rules.
