Creating secondary proxy addresses


Often times it may become necessary to stamp an additional SMTP address (proxy address) on a user account, either as part of a migration, or organizational domain name change etc…  

Here’s a VBScript example of how to add a new SMTP domain name to each user account in AD, preserving the user’s name (everything to the left of the @ in the address), and leaving the Primary SMTP (Reply-To) address the same.

Just change the highlighted text in the strQuery line to reflect your domain.  If you want to restrict the focus to a specific OU you can add OU=xxxx before the DC=.

You’ll also want to replace the newproxyaddr.com text in the second highlighted line to reflect your new smtp domain that you want to add to each user.

    I haven't used this script in over 2 years, then suddenly twice in the same week!

    Then, I discovered today that in the very rare case where the DistinguishedName field might contain a forward slash (ie. a notes migration), you will receive the error :

    (null) 0x80005000

    This can be remedied by adding the following line before the  Set objUser = GetObject("LDAP://" & strContactDN)  :

    strContactDN = Replace(strContactDN, "/", "/")

    This will use the backslash escape character so VBScript doesn't get angry…
