Have you ever asked how to add Exchange Server to an existing send connector and why you want to do that? The answer is pretty simple; you want to set up Exchange in High Availability and load balance the outgoing mail. If one Exchange Server is offline, the other can keep sending mail if you have an Exchange SMTP relay set up. If you have a DAG set up, outgoing mail flow will keep sending the emails to the internet.
By default, Exchange Server will not add a send connector. But, because this is our second Exchange Server, we will not create a new send connector. The send connector is available, and we only will add the Exchange Server as a source.
Configure Exchange send connector
Log into Exchange Admin Center and click on mail flow in the feature pane. Click in the tabs on send connectors. Select the send connector in the list view and click the edit icon in the toolbar.
Click in the menu on scoping and go to the section *Source server. Click the + icon.
Select the Exchange Server and click on the add button. Click OK.
Verify that the selected Exchange Server is added as a source server. Click on Save.
You did successfully add a second Exchange Server to the send connector.
