It is often necessary to create a Business Note for a contact when you are in a hurry.  To simplify this process, you can create a button on your Outlook toolbar:
1.) Verify that your security settings will prompt you to run unsigned macros by selecting "Tools | Trust Center..." from the main Outlook window. Then click "Macro Security" and select "Warnings for all macros" and click "OK"
2.) Create a Macro from the main Outlook window by selecting "Tools | Macro | Macros..."
3.) Type "Note" as the Macro Name, then click "Create"
4.) The Visual Basic editing window will open.  On the left-hand side is a project navigation pane.  Right-click on the top-level item named "Project1" and select "Project1 Properties..."
5.) Change "Project1" to "Business" and click "OK"
6.) In the main code area, you'll see "Sub Note()", followed by "End Sub". Replace those two lines with the VBA code below, then click Save.
7.) Close the Visual Basic window to return to Outlook
8.) Right-click on the Outlook toolbar and click "Customize..."
9.) Select the "Commands" tab, select the "Macro" from the Categories list, then drag "Business.Note" to the standard Outlook toolbar and click "Close"
on the "Customize" dialog.
10.) Select a business contact or account, then click the "Business.Note" button.
