HPE OneView Basic auth support removal September 2025

[CurlyHP]

According to Microsoft:

During September 2025, we will remove support for Basic auth with the Client Submission (SMTP AUTH) endpoints:

smtp.office365.com
smtp-legacy.office365.com 

Once Basic auth is permanently disabled, any clients or apps connecting using Basic auth with Client Submission (SMTP AUTH) will receive this response:

550 5.7.30 Basic authentication is not supported for Client Submission.

Can anyone advise if HPE Oneview can use OAuth and how to set it up?

HPE OneView today does not support Azure AD/MS Entra authentication for either user or SMTP.  We have been exploring options, but nothing to share at this time.
