Simple macro in Outlook to remove spacing: Object required error message

[CWL88]

I created a macro to remove spacing successfully in Word and it looks like this:
Selection.Style = ActiveDocument.Styles("No Spacing") -- with the appropriate Sub and End Sub.

When I created a macro in Outlook and typed in the same content, it did not work.
Error message was:
Run-time error '424':
Object required

What did I do wrong?

I am obviously a VBA newbie. I want to select text in an email and use a keyboard macro to remove spacing -- without having to right-click to access paragraph settings or open the email and go to Format Text.

Thank you.

Why would you expect Word code to work in Outlook?

Emails are not document files.

You want to edit an incoming email?

Hi June7,
I was hoping that formatting code that works in Word would work in Outlook. I thought the underlying editor in Outlook is the same 'engine' as in Word. Where can I go to learn the code(s) specific to Outlook?
Thank you very much!
