Exchange hybrid mail flow
Hi leng,
Please see the option 3 from the following article to meet your goal https://support.office.com/en-us/article/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-office-365-69f58e99-c550-4274-ad18-c805d654b4c4
Thanks Nuno,
i have seen that article and others that is a bit poorly written, at least nothing i can understand well.
What i ended up is the following:
1. In O365 Exchange ECP i edited the connector that is From Organization to O365 to use certificate containing *.domain.com
2. In on-premises exchange ECP, i created a new send connector to use domain-com.onmicrosoft.com as smarthost and also force this connector to use TLS and assigned it the same certificate used for OWA.
Since we have multiple domains, i was afraid using domain-com.onmicrosoft.com wouldn't work, since this is different for each domain. Anyhow, it worked :)
