I have Exchange 2010 SP2 environment and Postfix server as mail gateway. I successfully configured Exchange Hybrid Configuration and can move malboxes from on-premises domain to cloud and back.
MX record (tratata.com) in DNS point to postfix server with priority 10. On Postfix configured all aliases.
I need that all e-mails sended to Office365 and if the mailbox not found in Office365 and Exchage, must go to Postfix server.
How do I need to reconfigure the mail infrastructure?
Thanks for the feedback.
Sounds like you would create a mail routing loop if you did that. Here is your scenario:
Message from Internet --> Postfix --> Exchange 2010 --> Deliver or forward to O365
If you configure O365 to re-route mail back to on-prem it would endlessly loop. Maybe I am just reading this wrong?
Sorry to say but no, catch all email addresses are not allowed in Office 365.

Thanks for your answer!
I would like configure like "catch all" in Exchange 2010. Do I have the ability to configure the "catch all" in Offise365?
