setting up an outlook account on Postbox

[Gérald Tenenbaum]

Has anyone succeeded in setting up an outlook account with security OAuth2 (Microsoft) in Postbox?

It seems that Microsoft requires smtp-mail.outlook.com but it is impossible to set this in Postbox: when you fill up the field with this value, Postbox silently replaces OAuth2 (Microsoft) by OAuth2 (Google) and sending fails.

When you use smtp.office365.com all emails to a Gmail account bounce back beacuse of an authentication issue.
