We have already seen about the usage of developer menu in creating templates for outlook 2010. In case if you do not find the developer menu in outlook 2010 then you can enable it using the customize quick access toolbar in Office 2010.
Navigate to Outlook 2010’s quick access toolbar and click the arrow pointing downwards and select More Commands from the menu list.
In the Outlook Options window, click Customize Ribbon option and Under Main tabs, mark the check box with menu with label as Developer. This would now display the Developer men in Outlook 2010.
