  • Hi,
    Yes, every recipient created in Exchange has a legacyExchangeDN and that is the value you would want to export before you remove the mailcontacts so that you can import it again to avoid users getting NDRs when you have recreated the recipients.

  • Hi,

    Do you want to recreate mail contacts or mailboxes ?

    Mail contacts haven’t legacyexchangeDN and proxyaddress, because there isn’t a mailbox in your exchange organization.

    If mailbox is what do you want recreate, why don’t you move mailbox to new server instead of recreating ?

  • Thank you.

    I thought legacyExchageDN is always created when creating contact.

    When I created contact manually, it has legacyExchangeDN value.
