On this page we have the icons you may see in your Inbox, Sent folder, or in the message header. In most cases, Outlook 2007 (and Outlook 2010) use the "New" icons introduced in Outlook 2003, however, if the icon is different it is listed under the Outlook 2007 column.
Outlook 2013 aims for a cleaner look and many default icons, such as read and unread envelopes are gone. In the case of Unread, the envelope was replaced by a blue bar to the left of the message.

When you download headers only (usually IMAP and Exchange offline mode), you'll see the following icons in your Inbox, indicating the status of the message:
Only the message header was downloaded:
(Outlook 2002 and older)
When a header is marked for deletion, the icon includes a red x ( ).
An icon with a small blue down arrow arrow () means the message is marked for download.
This screenshot shows the 4 options you'll see when you download headers only.
The first message is marked for deletion.
The second message is completely downloaded.
The third is marked for download.
The last is the header only – it's not yet marked to download or for deletion.
In Outlook 2003's preview pane or in an opened message you may see either little messenger icons (pre-SP2) or balls. These indicate if the sender is online with Windows Messenger or MSN Messenger. (This a sample of the icons you'll see – there are more icons than just these icons.) Note, in later versions of Outlook, the icons are square, not round.
