By default, as soon as you select an email message, Windows Live Hotmail will automatically mark it as "Read": visually, this means that the email sender's name is no longer bold (see screenshot). But what if, after reading it, you decide that you want to postpone acting or replying to this email for the meantime? Easy, you just mark the selected email as Unread, to remind yourself that you need to come back to this message later on.
Tip: in an effort to make Hotmail behave more like a desktop email client, the Windows Live team has added support for quite a few keyboard shortcuts common with Outlook, the email program of the Microsoft Office suite. Just like in Outlook, you can now use Ctrl+U to make the current email message as Unread, and Ctrl+Q to make the current message as Read. (Both keystrokes also work if you have multiple messages selected at the same time!)
Follow these steps to mark an email message as Unread in Hotmail:


Tip: the next section of this tutorial assumes that you already know how to select multiple emails in Hotmail (if not, quickly read that tutorial!)
To mark multiple emails as Unread at once:
The name of the sender of all selected emails will now appear in bold, indicating that these emails are Unread! (In older versions of Hotmail, these emails would be displayed with a light yellow background.)
This is perhaps the least important part of the tutorial, since Hotmail automatically marks as "Read" emails you open to read. But you can manually mark a message as "read":
Note that emails will be marked as Read or Unread also from an email program like Windows Live Mail, if you use it to check your Hotmail account.
