Many users who need to send out a standard reply on a regular basis save a copy to Drafts then try to figure out ways to reuse the draft. While this is not the best method for reusing boiler plate messages, if you choose to do it this way, copy the draft (select it, Ctrl+C, S) then use the copy for the new message. Or select the message and click Forward to begin a new message based on the draft copy.
You could also use Autotext (Quick Parts in 2007/2010) to insert blocks of text. However, its just as easy to create a template and they work well for larger blocks of text.
To use Templates: Create the message - in Outlook 2003 and older you need to use the Outlook editor or choose Actions, New message using Outlook in order to save as a template.
Save it using the File, Save as menu and select template file type (*.oft). This will default to the template location, usually a folder deep in your file system (in Vista, its C:\Users\user\AppData\Roaming\Microsoft\Templates\) . Change this to My Documents or other location that is easy to find and save.
Open Windows Explorer and locate the template then drag and drop it into a folder in Outlook. You can drop it in Drafts or create a Template folder. I like to use one called .Template - the dot puts it at the top of my folder list so I can find it quickly.
Another option is publishing forms to any folder in Outlook. When you do this, the form is listed on the Actions menu when you are in that folder. To use this method, look on Tools, Forms, Publish this form as and select a folder (in Outlook 2007, show the Developer tab to see Publish.) There are some issues with published forms and unless there is code used in the form (which requires publishing) or you use Exchange's organization forms library, a template is recommended.
AutoText & Quick Parts
Either Autotext or Quick Parts allows you to create a large text block to insert as needed. Insert it by selecting it from the menu, or type the first few letters of the text entry and press enter when it comes up in the screentip.
