Here we show you how to make Outlook mark them as read as soon as they’re opened.
By default, Outlook will not mark a message as read until you select another message.
Open Outlook and smack the “File” tab.
On the backstage screen, click “Options” in the list of items on the left.
On the Options dialog box, tap on “Mail” in the list of items on the left.
In the Outlook panes section, poke the “Reading Pane” button.
Only one of those two check boxes can be selected at once.
Click “OK” to accept your changes and kill the dialog box.
Click “OK” on the Options dialog box.
Outlook is a great email client, but like most programs, it has its quirks.
you could also suspend the Reading Pane if you don’t want messages automatically opened when you select them.
