I am using macro button fields in an .oft email template in Outlook to use as placeholder text so users can edit these templates more easily.

However, I'd like to run a macro before sending that checks to see if any macro button fields still exist in the body of the email (i.e. haven't been filled in/replaced with text).

Please could someone help me with this? I'm fairly familiar with vba in Excel but vba in Outlook is completely new to me and I understand that fields like these are actually Word features so I don't know where to start!

Thank you!
