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

    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.
