Good day Pete,
From my testing with Office 365 and Custom SMTP Server using OAuth 2. MFA is not supported.
You would need one 365 account to do the SMTP integration Authentication, (Disable MFA for this user), and have this account added to each production mailbox that will be used on GC as a Send As Delegate.
I used the info from here: https://community.genesys.com/discussion/smtp-oauth20-set-up
You can find very basic steps to achieve Customer From via Custom 365 SMTP Server attached.
Hope this helps.

Hi Robert,
Please bear with me. My SMTP knowledge is limited.
I am in the process of configuring Email in GCcx, Using the Custom SMTP Server integration to have emails from GCcx show from the client's email domain. For their office365.com email service, they have a company wide policy that Outlook require MFA. If this integration does not support MFA, then they will need to create an exception policy for the email accounts that will be managed by GCcx. They are looking for documentation stating that MFA is not supported, for their Security & compliance team, to approve the policy exception.
I appreciate you sharing your knowledge!
Thank You in Advance.

Two ENTIRELY different technologies. SSO and MFA are for authentication and SMTP is a transport. Now, with SMTP, you can use TLS or Oauth for authentication, but with services it would be difficult to use SSO/MFA. There are other authentication methods for web services that we can take advantage of programmatically.

Hi All,
I have a strong belief that MFA is NOT compatible with "Custom SMTP Server" integration, but I am in a position where I must have a definitive answer. I have searched the various GCcx resources, and can not find anything on this point.
Does anyone have a definite answer and/or a link to documentation of this?
