I recently started using my Outlook 365 on my new Mac and I found out that I have a problem with some e-mails that I send. I am Czech and thus I send most of my e-mails in Czech and we have a lot of special characters like "ěščřžýáíéůú" etc. I can type all of them and when I send them, in sent messages I see the correct version of my e-mail. But my recipients see the text of the e-mail without the characters. An example - instead of "stížnost" it reads just "stnost", the special characters disappear. I tried googling and looking it up within the outlook settings and I got nothing.
