Mailflow from On-premises Exchange to Gmail RRS feed

  • Question

  • Hi Team,

    Many thanks first of all, our client is currently enabled with Hybrid deployment of Exchange 2010 on-premises and Office365. Now, the scene is that they are migrating mailboxes from Office365 to Gsuite. So, external mailflow will be taken care once MS record is being changed, but we have internal applications installed on-premises domain which will trigger emails and currently through a relay it is being forwarded to on-prem exchange and from their to Exchange online.

    Now, the concern is once the mailboxes is moved to Gsuite, client will remove the licenses of Exchange Online accounts. So, we need to handle the internal mailflow to Gsuite, I fairly have an idea but have not done this in my career before. So, requesting to please guide as what could be done so that the mailflow can be handled?

    Many Thanks,

    Niru

  • Hi Manu,

    We found out a way to handle this situation. What we did was added the SMTP relay details of the on-prem domain associated with Gmail directly onto our smtp relay, so the issue is resolved.

    Many Thanks,

  • Change the mailboxes you move to GSuite into mail contacts or mail users with the target address set to the GMail address.

  • Hi Ed,

    Thanks for the reply, but for to convert each and remote-mailbox to Mail-Contact it would take a huge task. So, is there a way for us by implementing a policy or anything like that?

    Many Thanks,

    Niru

  • Hi Manu,

    The above suggestion was helpfull but it will take a lot of efforts. So, would there be any other way then probably I could alone complete the task and easy to manage the change.

    Many Thanks,

  • Hi Niru,

    I am afraid not, maybe we could write a script to create a batch of the mailbox contacts or users.

    You could refer to this: Bulk Create Exchange Contacts via PowerShell
