I recently released Excorporate 1.1.0 to GNU ELPA.  Excorporate allows Emacs users to retrieve calendar entries directly from an Exchange server such as Office 365, without the need for external programs.

The latest release adds experimental OAuth 2.0 support, via a new library I wrote and published to GNU ELPA, called url-http-oauth. With Excorporate 1.1.0, I can access Office 365 again.  A while ago, the server to which I connect had disabled password-based authentication — including application-specific passwords.

I haven’t heard any success reports from users yet, so I wanted to mention the update on my blog. Soon I’ll write a followup post about my thoughts on OAuth 2.0 from a client implementer perspective.
