VBA - Stop program from quitting, minimize instead

I want to write a macro for Outlook that is called when I click the X. I want the Application_Quit() subroutine to stop the program from quitting, then minimize 开发者_运维知识库it instead. I can figure out the minimization, but how to I prevent it from quitting?

Not truly possible to prevent the close. You can tell based on the method signature of the Application_Quit() event:

   Private Sub Application_Quit()

   End Sub

A cancellable event will look like this:

   Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)

   End Sub

I searched around, and found a kind of cool hacky trick, though, if you don't mind the side-effect that Outlook automatically minimizes when it launches (found on this forum, copied and reformatted):

Trick is to add a macro that auto-minimizes Outlook when it starts:

Hit Alt-F11 to go to the VBA editor. Paste this sub in the "ThisOutlookSession" section:

Private Sub Application_Startup()
    SendKeys ("% n") 
End Sub

Now after Outlook loads it will minimize. I also use this next one to minimize instead of close when someone attempts to close outlook.

Private Sub Application_Quit() 
     Call Shell("C:\Program Files\Microsoft Office\OFFICE11\relaunchOL.bat" _
       , vbHide)
End Sub

Create C:\Program Files\Microsoft Office\OFFICE11\relaunchOL.bat and put these two lines in it:

Ping 1.2.3.4 -n 1 
"C:\Program Files\Microsoft Office\OFFICE11\outlook.exe"

This will give Outlook a couple of seconds to close, then relaunch itself, then minimize itself sinse you have the macro for minimize in startup.
