Apple Mail Duplicating Every Email
There was a dicussion on this earlier this year but no one figured it out and the thread was closed so I wanted to post this. It's an easy fix!
- Quit Mail
- Delete the preference file com.apple.mail. file path: /~/Library/Preferences/com.apple.mail.
Keep in mind that if you had any custom settings, you'll need to redo them, but the accounts are unaffected.
