Outlook: come fare uno screenshot dell'intero corpo e-mail senza scorrere

Question

Bascialmente il mio titolo spiega il mio problema. Sto usando OL2010 e voglio essere in grado di fare uno screenshot dell'intera e-mail (non solo della "schermata").

Può essere fatto? Forse con VBA o un programma esterno?

Grazie! Mike

C'è un Domanda simile su come raggiungere questo obiettivo usando C#. Presta attenzione a questa risposta, spiega perché ci sono casi in cui potrebbe non essere affatto possibile.

Per un codice di esempio VB su come acquisire schermate, vedi Questo articolo da Microsoft. Ecco le parti più rilevanti:
