Hi @bertram12
Glad to hear this issue has been resolved! Thanks for the sharing.
However, due to a recent update in forum policy, the question author now is not able to accept their own answers.
So, I have written a brief summary of the solution this issue. Please feel free to accept it as the answer, which would benefit others who also has similar issues in forum.
[Aptos (Body) font suddenly appeared in Outlook 365]
Issue: Fonts in Outlook messages have big spaces.
Solution: It is caused by a button on the ribbon called "Immersive Reader". I don't recall clicking on it, or even recalling it was there. I don't even know what it means - and am too tired to look it up. I just clicked on it and the "kerning" issue (too much space between letters) has gone, and my Emails are left-justified (rather than centred) once more.
In addition, please kindly note that Microsoft Q&A forum recommends asking one question per thread so we can better focus on one question. It would also make searching answers easier for other community members. For other problems, you can create a new thread to better investigate. Thank you for your understanding and patience!
