(Android™) Office365 OAuth2 Resource Owner Password Credentials Grant for SMTP, IMAP, POPDemonstrates how to get an OAuth2 access token for use with Office 365 in the SMTP, IMAP, and POP3 protocols using the resource owner password credentials grant. This is a way of getting an OAuth2 access token for the O365 account you own, WITHOUT needing to grant access interactively via a browser.
