Remove LegacyDN from Exchange 2010 RRS feed

  • Question

  • Is there a way to remove or modify the legacyDN from all mailboxes.  the current value is

    /O=<non-existant org>/OU=EXCHANGE ADMINISTRATIVE GROUP (**********)/CN=RECIPIENTS/CN=<mailbox user>

    /O=shows an org that was a partner and has been gone for a few years.

  • Hi John

    Changing the legDNs of existing users is possible, but not a requirement. That is  not going to harm us in any ways.

    Steps to change:

    Open ADSIEDIT - connect to default  domain partition - locate the user account - right click and choose prooperties and there you can find legacy exchange DN value

    Note:
    Although you can change the LegacyExchangeDN of the user for any workaround 
    it is definitely NOT RECOMMENDED to change the LegacyExchangeDN of a 
    user. Doing this will cause problems with mail flow and free busy. It is not 
    recommended and not supported by Microsoft.
