During a remote help session, I ran across an interesting OWA toolbar today - please look at the attached screenshot.
The toolbar appears as a floating toolbar with the "Home" and "View" options above it. I have never seen Home and View as options over the OWA toolbar. I clicked on the ellipse and then on customize. I was given the ability to group items together. This is in Outlook on the web - Office 365 education. The User had OWA open in Chrome browser.
I cannot replicate this version of the toolbar in my OWA.
Any ideas of how this was produced. My User has no idea.
