Hi folks,
I must admit I'm finding the domain name business very confusing.
I currently have an on-prem Exchange 2010 SP3 environment in place using our own domain name. Call it contoso.com. I have created an Office 365 tenant and added the contoso.com domain to it successfully. It is our plan (in time) to fully migrate to Office 365, but we are going about this by means of a hybrid configuration.
When I began this exercise, my thought was that I would add contoso.com to my Office 365 tenant and set up a hybrid configuration. Mail bound for users with mailboxes in the cloud would hit our on-prem Exchange servers and get routed to the cloud mailbox. Outbound mail from the cloud would get routed out through our on-prem environment as well. In time, we could just switch our MX records to Microsoft's Office 365 servers and get mail delivered directly when we finishe the migration.
Is this possible, and if so, how would I go about configuring it? I've completed the hybrid configuration wizard, but I can't see users with cloud mailboxes in the GAL. When I try to mail a cloud user @contoso.com, it bounces with an invalid address error, although they can be mailed @contoso.onmicrosoft.com.
Issuing the 'get-remotemailbox' command in the EMS gives no results.
What am I doing wrong, or what haven't I done? Thanks for any help,
