Confirmation of emails in Intercom through Outlook in outlook outgoing/sent folders

After starting a conversation or sending/responding in an email thread within intercom, is there a way to see it actually in the “sent” folder within outlook? I feel as though I cannot confirm if all my messages are actually being sent or leaving from my email address. I don’t like not being able to access outgoing messages from within outlook if they're sent from intercom but using the same email address..? Does anyone have any insight on this?
