"Sub or Function not defined" when trying to run a VBA script in Outlook

Question

As a first step in creating a VBA script to resize a currently selected image to 100% x 100%, I'm trying to reproduce the example in http://msdn.microsoft.com/en-us/library/ee814736(v=office.14).aspx. The macro is very simple:

Sub Test()
   MsgBox ("Hello world")
End Sub

The VBA script was simply created in "Project1" which opens by default when one presses Alt+F11. However, I keep getting the error "Sub or Function not defined" when trying to run the VBA script (Figures 1 and 2).

How can I make the VBA script 'accessible' to Outlook?

Answer 1

I solved the problem by following the instructions on msdn.microsoft.com more closely. There, it is stated that one must create the new macro by selecting Developer -> Macros, typing a new macro name, and clicking "Create". Creating the macro in this way, I was able to run it (see message box below).

Answer 2

I need to add that, if the Module name and the sub name is the same you have such issue. Consider change the Module name to mod_Test instead of "Test" which is the same as the sub.
