You can also have it the other way round, though: beginning a message with its recipients from the Windows Live Hotmail address book.
Send a Message to Someone in Your Windows Live Hotmail Address Book
To compose a message to a Windows Live Hotmail address book entry:
- Select Contacts from the left Windows Live Hotmail navigation bar.
- Make sure the boxes next to the desired recipient or recipients of your message are checked.
- Click Send email in the toolbar.
Windows Live Hotmail now sets up a new message with the recipients already entered in the To: field.
