Using Classic Outlook on Windows for personal email, calendar, and contact management
I've just 'upgraded' (if you can call it that) to the new version of Outlook and instantly got frustrated by this. I could be imagining this, but it seems like if I double-click quick enough, like as quick as I can, then it opens in a new window, but if I'm too slow then it opens in the reading pane.
It doesn't seem to have anything to do with the double-click speed set in the mouse settings.
