Mail fail to open, Not responding imac late, 2013, os 10.11.6, happened suddenly this morning
The last mail i received was at 08:20. Then all mailboxes went offline: The little "lightning bolt.'
I couldn't get the boxes back online. I tried closing the app. It wouldn't re-open.
It comes up, takes its shot, and goes to the beachball of death and I have to Force Quit.
Same in Safe Mode.
I can get to some of my mail in the icloud at my 'mac.com' address but not for my 'me.com' one.
Any help would be greaatly appreciated, thank you.
iMac 21.5″, OS X 10.11
