Hi @worldandword ,

Normally the bellow should be the best option and what you need.
It is normal that the first one option fail if there is no identity federation in place between both organizations what I guess is actually not the case.
It is possible that this federation is by default present with outlook.com since it is still Microsoft but private ( haven’t tested it personally but would make sense).

smtp server:smtp.office365.com
port:tried(25,587)
connecting using ssl:true
this smtp server requires authentication log on as notify@xyz .com
from notifiy@xyz .com
to user@jaswant .com

You could use shared mailbox to avoid waste of licenses.

Hope this would be helpful

Regards.
