Multi tenant moving one tenant/domain to Office 365 RRS feed

  • Question

  • Hello All,

    I ask for your forgiveness if this double posts.  I was trying to re-categorize this and this is my first time using the Technet forums.

    We have an in-house Exchange 2010 Server.  It runs WebsitePanel and we have multiple clients on it.  This weekend, we used SkyKick to migrate our domains over to Office 365.  Everything is flowing correctly for all external mail and inter company mail.

    The issue arises when one of the other tenants on the server sends email to our domain.  It delivers it to the old (in-house) Exchange server instead of sending it to the Office 365 server. 

    We don't want to shut down the old servers for a few days just in case things are delayed in routing changes due to DNS, etc.

    How can I make the other tenants follow the path in the MX record and deliver to our migrated domain at Office 365 instead of sending it to the "internal" old domain that is still on the same Exchange server?

    Any help or thoughts would be greatly appreciated,
