The update brings the look and feel of the Windows 8 app back - and that's a good thing. You can quickly switch between email accounts and also see the number of new emails in each Inbox.
UI customizations
The dark theme exists! Change to a dark theme and also stretch the background image.
Reading options
Mark items as read options, including setting a timer on how long before the view changes.
Nix Conversation view
One of the more requested items, you can now eliminate the Conversation view option.
Privacy
Let Office? There's a confusing message here. However, using this option you can opt to protect your email privacy.
Versioning
The update takes the version to 17.6224.42281.0
Calendar, too!
Don't forget that the Calendar app is part of the deal. It gets a dark theme, too. Additionally, the UI changes make it a much more usable experience.
Family resemblance
The Windows 10 Mail and Calendar app is getting much closer in feel to its big brother, Outlook.
