How to correctly organize synchronization with microsoft outlook in an android application?

Question

Android

I am developing an application, one of the users asked for synchronization with microsoft outlook. I got acquainted but did not fully understand whether only mail (login) and password are enough to receive mail and server parameters, or is it necessary to access the account and work through it? It's just not entirely clear in what modes microsoft outlook can work. I found information that there is a Microsoft Exchange Server, it can be on the server both on the client and on the microsoft server, can there be any difficulties with working from the application?

Since Exchange 2007, an EWS service has appeared that needs to be published.
The interface is specially designed for such tasks.
Publish, study the API - https://habrahabr.ru/post/117268/

Or the old fashioned IMAP4.
