I have two domains configured in Office 365. For outbound mail routing, there's currently a single connector, configured as:
From: Office 365
To: Partner Organization
Use: All domains
Route Mail: Through smart hosts (MXLogic)
As part of moving this from MXLogic to ESS, can I put both outbound mail servers for the domains in the connector? That's how it currently is for MXLogic. Otherwise, do I have to create rules to route specific source domains through specific connectors? I started looking at that, but when I try to route to a connector, it tells me there are no connectors available. Is that due to the type of connector?
Any help sending from multiple domains in Office 365 through ESS is appreciated.
