Compose Outlook Email Without Sending

I am trying to write a macro to compose an email in outlook without sending it. Ideally the macro would compose the email and the email would be left open for me to inspect before sending. Below are the details.

Column A contains the addresses
Column B contains the CC addresses
Cell C2 contains the message

I can change where the above info is located/arranged if need be.

My spreadsheet automatically generates the email addresses, which are dynamic. For control purposes my employer does not want me to have the email automatically sent, being the reason for me to want to inspect the email before sending it.
