When I list unread emails in Microsoft Outlook web interface:

enter image description here

then open one of the unread emails, the email is still marked as unread.

Is it possible to change Microsoft Outlook web interface's settings so that opened emails are marked as read?

This looks like a bug in Outlook's settings when viewing using Filters. However, you can work around it by manually marking the email as read when you have it open. To do so,

  1. click the ellipsis icon in the email actions shown above the message (when it's open) enter image description here

  2. click the "mark as read" option from the dropdown menu. enter image description here

Now when you close the message and return to the filtered list view, it will no longer appear as "unread"
