SMTP Mail in Multi-Tenancy Environment

(0) ShareShare
ReportReport
Posted on by 16
SMTP Mail in BC is driving me a little to distraction.
 
Our BC Tenancy is separate from our Logon Tenancy due to local currency needs, all users are added as Guests to the BC Tenancy and and BC itself is fine but, I cannot get SMTP Mail to work (or any sort of mail), I am sure this is down to Basic Authentication issues but, that looks still to be turned-on in our Logon Tenancy although it may be turned off globally, searching makes it very hard to tell whether it is still supported at all.
 
I also can't find any way of enabling App Passwords because we are fully MFA.
 
Does anybody have a similar configuration in which they have managed to get mail to work in any way as I have run out of ideas ?
