SOLVED: How to Use Email Templates in Outlook 2013 (or 2010)
Well the answer is, use Word 2013 to send your email. You may not be aware that Outlook dropped its own text editor somewhere around Office 2000, so when you are creating an email in Outlook, you really are just using Word. The problem is that Microsoft removed the EMAIL links from the typical ribbons in Word. Fortunately you can easily get them back:
Open Word 2010 or 2013, click FILE then OPTIONS
Click QUICK ACCESS TOOLBAR, and then click ALL COMMANDS in the Choose commands from list
In the list that appears, click SEND TO MAIL RECIPIENT, and then click ADD to add the command to the Quick Access Toolbar
Now in Word 2010/2013 you can:
Click FILE > NEW and select a template
Adjust your message as you see fit
Click the SEND TO MAIL RECIPENT icon in your Quick Access Toolbar (top left corner of Word)
