Can I permanently increase the font size in the reader pane of Outlook?

nailed it bro.

No, the slider isn't present on the 'New Outlook'!!!!!!!!! That is the point! I like the new outlook rules and some things but I have to keep going back to the 'old' outlook when I need to increase the font.

I am sorry to hear that Microsoft has chosen to write off all customers over the age of 45. Being able to permanently set the font size to something that users can read without difficulty seems like a pretty basic user experience feature. I have low vision and find the 8 point default that Microsoft seems to think is adequate for everyone does not work. I have a 24-inch monitor and I still need to use a magnifying glass to read my mail. I tried Ctrl-+, which works for most software, but NOT Outlook, and I had to search Google (not Bing) to find out that font sizes are buried in View -> Current View -> View Settings -> Other Settings to get to any font settings, and it still does not include the reading pane. Another Google search tells me to go to View -> View Settings and use the + and - to adjust the font size, but I can't find the right place where this works. I can only hope that Microsoft's User Experience team soon reaches the age where they have to deal with these problems and see what a mess they created and how difficult the Outlook UI is to work with.

There IS a permanent way to increase the size in your reading pane.

In the lower left corner of Outlook, manually increase the size using the slider. Once you're at your desired zoom, click on the number (e.g., 120% or whatever you've selected) at the far bottom right. A dialogue window will appear. Click "Remember my preference" and then click OK.

That worked for me thank you.

I see that many people want this, and this conversation was 2 years ago. I am sure the coding could be done by an intern for something so simple to roll out in the next update. Curious why it hasn't been done yet?

Thank you
