Mark As...

You can now mark your incoming messages as:

- Read
- Unread
- Importance High
- Importance Low
- Importance None

Changing a read message back to the unread state can help you to make that message more visible so you won't forget to get back to it later.
The importance mark can also be changed, so you can make a message more or less important to you regardless what importance was set by the sender.
In order to mark a message, select the checkbox of the message you are interested to and select a menu item from the "Mark As..." dropdown menu available in your mailbox command bar.
