Office365 support

Heard about mailspring being open sourced and wanted to give it a try today.

Went to setup on an office365 account and got an auth error after the signin at microsoftonline:

OAuth Code exchange returned 400 Bad Request: {"error":"invalid_request","error_description":"AADSTS9002327: Tokens issued for the 'Single-Page Application' client$

We do use Okta for SSO, not sure if that kinda setup breaks auth in some way for MailSpring.

Any idea’s?

I’m facing the exact same issue. Everything looks good until you get back into Mailspring. Also returns You're all set!.
