Dear all,
There has been few threads about Mail app crashing involving the junk filter but my problem is a little different.
My filter was working wonders until on training it one day, it crashed the application. I realised that the default Junk mailbox had disappeared of the mailboxes list. Creating a new one did not solve the problem.
If anyone could help me reset this default mailbox I would really appreciate.
Alternatively, I could back up (and have) my mailboxes but don't know how to reinstall Mail app. without reinstalling the all OS X system.
Thank you for your help.
