Hi,
I have a problem that is proving very difficult to solve, and I'm hoping someone on here might know a bit more about this.
I am trying to configure MS Exchange Online to route all emails through Amazon SES as a relay server, however the problem is that SES seems to want you to pass it SMTP username and password credentials to authenticate with, and I don't think Exchange Online allows for this?
I have checked all the options in Outbound Connector section and there doesn't seem to be any place where I can choose SMTP authentication. On Exchange 2013 and on-premise 365 Exchange solution I believe you can do this, but with pure Exchange Online I'm not sure...
Does anyone know whether this is possible, and if not why Microsoft doesn't allow it / if they might be intending to enable this in the near future?
Thanks a lot in advance!
Tom
