Multi-factor Authentication for Microsoft 365 Email

Microsoft 365 started deprecating IMAP "Basic Authentication" (ie. username/password) on October 1, 2022. Since then I have been unable to send emails or validate my Microsoft 365 email account in Lightroom Classic.  It says "Validation failed.  Failed to establish connection with the outgoing email server."

 

Microsoft told me that they still support IMAP multifactor authentication, and it would start working with any email client with "Modern Authentication" (ie. username/password/multifactor).  Is this available in Lightroom Classic?

 

Details: Lightroom Classic v12.0 on Windows 10.

I will second this behavior. I checked the Azure sign-in logs and the email manager is attempting to connect SMTP Basic Authentication. Does anybody know if Adobe plans to update this integration to be capable of connecting to a 365 Modern Auth account (regardless of MFA addition). We use Modern Auth to SSO for Adobe Creative Cloud, you would think it could just use that token to connect to 365 email.

I will also add the new behavior of Lightroom Classic crashing when I try to access email manager settings with Microsoft Outlook (365 version) as my default mail client, guessing for the same reason, my Outlook is signed-in with Modern Auth.
