    Thanks for sharing this information.

    We are trying to migrate thousands of DL's based on Business units. I am sure this will be very helpful. Will be trying some test with few DL's and see how that goes.

    TonyRedmondHi Tony and thanks for all the great info you've provided in this thread.

     

    I'm getting ready to do a migration this weekend it looks like (have a Ex2010 Hybrid /O365 setup) and all my user's mb's are already up in the cloud but we have a lot of on-prem DG's.

     

    Is there a PS command to pull the list of users for a specific group and save to a CSV?

    Get-DistributionGroupMember ???

     

    And then the corresponding  PS-online command to create the DG with the CSV list of users?

     

    Maybe I missed it above but thanks!

      Get-DistributionGroupMember -Identity MyGroup | Select DisplayName, PrimarySmtpAddress | Export-CSV -NoTypeInformation c:\temp\DL.csv

       

      Something like that...

        TonyRedmondgreat! thanks for fast reply! I'll give that try right now. By any chance do you know what it is for writing it or the Exchange Online side?

         

        If not I'll open a case. Thanks again!
