Emails sent from Mail looks terrible with different fonts, sizes etc.
I have discovered that emails sent from Mail in OSX 10.11.3 looks different on the recipients computer. My default font is set to Calibri size 15 and I have chosen "Formatted text" when composing new emails. When I look at my emails at my recipients computers (different PCs with different versions of Outlook) it looks completely different. Parts of the email shows up with my standard font settings and other parts seems to have the Windows default settings (Times New Roman).
I use my computer for business purposes and this looks totally unprofessional, does anyone have a solution to this?
