Automating Email Sending with Different Mailboxes

Hi everyone,

I’m working on building an automated email sender system that utilizes the OpenAI API to generate emails. I've been reading through the documentation regarding the Full Access and Send As permissions in Outlook, and I have a specific implementation in mind.

I need to create a system that allows me to send emails from different individuals' mailboxes within my company while also being able to view the reply threads. My question is:

Is it possible to achieve this by obtaining the OAuth token just once and then using it to send emails from different mailboxes, provided my IT admin has configured the necessary permissions accordingly?

Any insights, experiences, or additional considerations would be greatly appreciated!

Thanks in advance!
