I am using Macbook pro with latest Elcapitan OS. and Microsoft office for Mac 2011, outlook version 14.5.9 (151119) for mails.

Other non mac users also use outlook for email exchange (windows based OS users)

My font settings in outlook are : Calibre 16 for both in HTML message (proportional) and plain text messages (fixed with).

Other preferences used are "while replying or forwarding use format of original message"

My question is "while sending the mails from outlook to other non mac users with microsoft windows based, few users receive emails with font size less than 6 size". we have checked their mail setting for font etc. and found similar to other users. However they receive mails in very small font from me"

pl. help to resolve this issue
