Right-click on the desktop and select New / Shortcut. In the location, type:
mailto:to.address@somedomain.net?Subject=Test%20Message&Cc=ccrecip@anotherplace.org&Bcc=blindkopy@foo.com
Let me break it down for you:
Primary Recipient Address(es)
mailto:to.address@somedomain.net
'?' Introduces Parameters
The Subject (note: spaces entered as '%20')
Subject=Test%20Message
Recipient(s) to receive 'carbon copies'
Cc=ccrecip@anotherplace.org
Recipient(s) to receive 'blind carbon copies'
Bcc=blindkopy@foo.com
You can specify multiple recipients for any of mailto:, Cc, or Bcc by separating them with semi-colons (';'). Everything after the primary recipient's address is optional. Any or all may be omitted. Also, each parameter and values must be separated by an ampersand ('&').
Finally, after entering your entire 'mailto' string in the address box, click 'Next' and name the shortcut anything you like. Finally, click 'Finish.'
When you double-click the shortcut, Windows will open a new message in your default mail client and fill the appropriate fields.
If your shortcut contains only 'mailto:' with no other information, Windows will open a new message with none of the fields filled. Also, you can do the same thing by clicking Start / Run (or Windows-key + 'R') and entering the 'mailto:' in the Run box.
Fantastic! Thanks so much. +1 plus accept. As to not sending until open, I have Outlook open at the time. – Xavierjazz – 2010-08-18T17:27:53.453
