Route mail between Office 365 and a GoDaddy email server

[DarinSpence]

I have @mydomain.com mailboxes in two places; some mailboxes in Office 365, and some are on a GoDaddy email server.  This article, "Set up connectors to route mail between Office 365 and your own email servers" suggests that I could setup a connector so that some @mydomain.com mailboxes could be on the GoDaddy email server, and some @mydomain.com mailboxes could be on Office 365 - but all mailboxes would be @mydomain.com email addresses.  

Is this true, or do all @mydomain.com mailboxes need to be hosted on Exchange Online?

p.s. My use case is that I have some contractors with @mydomain.com mailboxes, and it is really cheap to host those mailboxes with GoDaddy compared to buying them all Exchange Online accounts.

Yes, you can do this, though not a best practice, you can point your MX to O365 and then set up a connector with transport rule (CBR) to route all emails for contractors to that connector...

This might be helpful in creating Transport Rule and connector:-

Hi @DeepakRandhawa, I know this is old, But can you enlighten us with the link you provide? It seems as if that link does not work anymore. Based on my research, I have found these references to how to do it https://learn.microsoft.com/en-us/exchange/mail-flow-best-practices/use-connectors-to-configure-mail.... But It looks like I am getting errors when testing the connectors similar to this one, my research on this has been very unclear, Like this one here. http://forums.msexchange.org/m_1800559529/mpage_1/tm.htm Anything you can share on this can be constructive. Thank you.
