You cannot authenticate as yourself and get access to other mailboxes, even if you are an admin in the domain. HOWEVER, as a domain admin, you can whitelist your app to access all users in the domain. It involves using a service account with domain wide delegation. You need to whitelist your app in the Google Apps Cpanel and use a slightly different auth flow. See: https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority

Though really, email mistakes happen, just have them reply with a followup to correct the misinformation. Going and deleting the email from their mailbox, even if it's possible, seems like a really bad idea from a "user trust" perspective (what happens if you have a bug and delete the wrong mail!)--has someone tried reasoning with said person about this idea? :-D Users that have already seen the email may be worried/confused when it just disappears, etc.
