Collection of additional useful sample apps and libraries written using Rebex components.

WPF apps using Rebex Secure Mail to access Office365 with OAuth 2.0 authentication

Office365_OAuth2 - A set of two WPF applications (and a helper library) that show how to authenticate to Office365 (Exchange Online) using OAuth 2.0 and retrieve a list of recent messages with Rebex Secure Mail using IMAP, MS Graph or EWS (Exchange Web Services) protocols. Targets .NET Framework 4.7.2 and .NET 6.0.

Office365_OAuth2_Legacy - A backport of the previous sample app to .NET Framework 3.5 SP1. Uses Newtonsoft.Json for parsing OAuth responses

Office365_OAuth2_IdentityClient - Another variant of Office365_OAuth2. This one uses Microsoft.Identity.Client package for the OAuth 2.0 authentication flow. Also includes a third app that shows how to authenticate to EWS using app-only mode (suitable for unattended services/deamons).
