Do you want Microsoft Outlook to show messages as read faster or slower?
To adjust the setting, first go to File, then click Options:
Next, click Mail on the left side, then click Reading Pane on the right side:
Within the Reading Pane options you can add or subtract the number seconds before a message shows as read, or disable the setting.
Also, please note that Outlook also has the option to right an email and select Mark as read / unread:
