I did the upgrades, Windows 10 and Office 2016.
I am finding Windows 10 to be very tiny and difficult to read fonts, trying it with zoomed to 150%, not everything will display well.
I am also finding Outlook 2016 to be very white and bright and not much contrast and small fonts. I am changing fonts etc., as I can, but if anyone has any sites with the best hints to improve the display, please post.
Outlook 2016 has all my email addresses separately, but it does not show the number of unread emails in each folder when the folder is not expanded, my old substitute laptop with an old version of Windows live mail shows it. Has any one found a way to see all your email inbox folders on the left AND have the list of the number of unread emails so you know that something came in? I can create a single merged inbox with all accounts, but the list of outstanding emails on each folder is really quite nice.
