What I mean is Microsoft has deprecated the https://outlook.office.com/api/v2.0 APIs, but https://outlook.office.com/IMAP...ETC scopes (not Graph) needs to be used for IMAP/SMTP/POP XOAUTH2 to work. AFAIK, Microsoft has not announced any changes coming to the IMAP/SMTP/POP scopes.
So yes Graph APIs are the replacement for https://outlook.office.com/api/v2.0, but the problem is the Graph APIs cannot be used with the same access token we use for https://outlook.office.com/IMAP/SMTP/POP scopes.

I hope this makes it more clear what I'm concerned about.
