How to use the ADModify.NET tool to add an X.500 proxy address to multiple accounts

How to use the ADModify.NET tool to add an X.500 proxy address to a user account

Admodify2.1 nolonger support X500 tab entry, thus we will have to use custom tab.

 

X500 addresses are useful once we migrated volume of mailboxes from another organization and we enabled GAL sync between Exchange organizations before migration. Lack of the lagacyExchangeDN of old organization or x500 address, migrated users may get NDR once they tried to reply to existing emails to certain users.

1. Click the Custom tab.
2. Under Custom Attribute Set, follow these steps:
3. Click to select the Make a customized attribute modification check box.
4. In the Attribute Name box, type proxyAddresses.
5. In the Attribute Value box, type the X.500 address.
   
   For example, if you want an X.500 address of /o=OldOrganization/ou=OldSite/cn=Recipients/cn=mailNickname, type the following in the Attribute Value box:
   X500:/o=OldOrganization/ou=OldSite/cn=Recipients/cn=%'mailNickname'%
   
   
   In this example, we use the %'mailNickname'% variable because we assume that the mailNickname attribute in the new organization matches the mailNickname attribute in the old organization. If these attributes do not match, use another variable.
   
   Note If the migrated user account is from an Active Directory directory service environment, use the Adsiedit tool to locate the old legacyExchangeDN attribute of the user. Then, use the old legacyExchangeDN attribute for the X.500 address.
6. Click Multivalued Append, and then click Go.
