Email Client For Mac Os X Yosemite

Dear All,

OS X Yosemite: Take a Tour of Mail's Best New Features Apple But now that the public beta of OS X Yosemite is open, both developers and a large number of Mac owners are able to preview the new OS.

I have a problem after recently upgraded my Mac to Yosemite OS. I added my office email (*** Email address is removed for privacy ***), sending and receiving emails through outlook.com (for backup purpose). Before I upgraded my mac OS, the problem never exist before (my default address for sending email is *** Email address is removed for privacy ***.

The problem only happen when i send email through mac mail email client, but if i use my tablet and webmail, the problem do not happen.
