Email messed up ever since upgrading to Yosemite. The mail icon remains on the toolbar and I can open if I click into full screen and read the emails. I cannot send any emails. This is a huge problem.

My email has been completely messed up ever since upgrading to Yosemite. I am about to revert to prior OS because of this. I can't click on the icon on the toolbar. It is unusable. Nothing happens. The email will not open up at all unless I open email and then click View Full Screen. Even when I do this the email will not send from this computer AT ALL!! Off any accounts. If I logout and then simply go through Safari and open up yahoo separately then sometimes I can send email that way but this icon is useless to me now. The new operating system killed my email.

MacBook Pro, iOS 8.4

I’m not being a wise guy but I would suggest you install a new mail program, e.g. Firefox’s or Airmail. Maybe one of these will retrieve all your email. I’ve had to give up Apple’s mail since Yosemite and I’m now on current OSX10.3. Neither Apple nor any ‘10’s’ here were able to fix it and we spent several months of iterations only to end up thwarted.


It’s still a mystery non-solution. In my case I think the problem lies in my having had Apple ID’s for 30+ years, some

ending in .mac, .me and .iCloud, with multiple file categories under each. They just don’t seem to fit the OS system

which evolved into Yosemite, then Sierra, etc.


Maybe this info will help should Apple or others attack the software problem and file removals.
