Send an e-mail message based upon a template

Tip In addition to your own templates, you can download Microsoft Office Outlook 2007 templates on Office Online.
Keyboard shortcut To create a new e-mail message, press Ctrl+Shift+M.
If your template is saved in a different folder, click Browse, and then select the template.
Select the template you want to use.
