Can't sign into Outlook mail using System Preferences
I just got a new Mac Mini - my first Mac - and I can't sign into my Outlook mail in System Preferences. It keeps saying the password is incorrect.
In reality - I don't understand what is happening. I have Outlook signed into my iPhone and iPad; why isn't it working on Mac? Its using password verification to send messages on my iDevices, so its not like my password is wrong - or else I wouldn't be able to send messages. Any idea what is wrong on the Mac and my Outlook?
Thanks very much for reading!
Mac mini, OS X Yosemite (10.10)
