can I assume it’s outlook.com and not outlook from Office ?
If it is outlook.com, MS is doing a makeover.
Note: Outlook.com is being currently being updated. Some people will still see the classic version until we complete the update, and others will see the new Outlook.com experience. For more information, see Welcome to Outlook.com.
They have info here that may help:

I wish I had a definitive answer for you. Still not enough info.
I haven’t used outlook in awhile, but because of your questions, I set up outlook.com
The only font settings i see in outlook.com are for composing emails.
Any other size changes i can only seem to make by the browse zoom function.
let us know if you run across the answer and what the answer is.
Yes, it was Outlook.com. One of the free availabilities offered by my ISP.
I tried ctrl+O, and that worked. I still wish there were some more obvious way.
