RE: [Chrome on Mac Only]-Cannot scroll through conversation list in OWA for Office 365

I too was experiencing this issue. I was able to solve it by modifying the CSS of the scroll container in the page.

Here is the CSS I added:

.scrollContainer { z-index: 1; }

I have also created a Tampermonkey script for those interested: gist.github.com/.../c7d4c36c3390b5032fdf
