Can I make a shortcut to Send Outlook Email from Template?

For email templates I use a lot, I simply place a shortcut on your desktop linked to the template. All you need to do is go find your template in Windows Explorer, right click on it and choose Sent to > Desktop (create shortcut)

As it is stated in the article, here are the paths to the templates locations (unless you saved your template elsewhere);

Windows 7 and Windows Vista
c:\users\username\appdata\roaming\microsoft\templates

Windows XP
c:\documents and settings\username\application data\microsoft\templates

Then all you have to do is use the shortcut to open your template in one step.

I found some info about doing this with a macro, and it works in 2013, but I don't have 2010 to test it on.

If you don't have macros enabled, you will need to go into the Trust Center and enable all macros, which Outlook advises against doing because malicious code could run. Then you have to add a custom group to the ribbon and add macros to that custom group. Then you can get down to making the macro for a new message from a .oft template file. (more MSDN instructions here)

The macro code will look like this:

Sub TemplateName()
    Set msg = Application.CreateItemFromTemplate("C:\Users\xyz\Desktop\template.oft")
    msg.Display
End Sub
