Q: Mail app will not open?

I have been using the Mail app for a while on the latest version of el capitan but it has suddenly refused to open anymore?

 

I have restarted the machine & the app just hangs when I open it, no windows even open?

 

does anyone have an idea what to do please?

iMac with Retina 5K display, OS X El Capitan (10.11.4)

    Never use any kind of "anti-virus" or "anti-malware" software on a Mac. That's how you cause problems, not how you solve them.

    Obviously your problem has nothing to do with malware.

    Please open the iCloud pane in System Preferences. There is a checkbox marked iCloud Drive, and next to that, a button marked Options. Click that buttion, and in the sheet that drops down, uncheck the box marked Mail if it's checked.

    This Mail checkbox is not to be confused with the one, also marked Mail, that appears when you first open the  iCloud preference pane. They have different effects.

    Hi, thats it, problem solved !  Many many thanks Linc Davies.  Crazy that one checkbox can cause so much trouble.  I don't even recall turning that check box on?  Anyway, all appears to be fine now & I have all my old mail back & settings too, Bravo!
