Exchange GAL issue

I need to create mail-enabled users in my Active Directory environment who do not show up in the global address list (putting a check in the "hide from Exchange address lists" is not an option.)

Can I do this by creating a new Administrative Group?

Our domain is 2003, Exchange Server 2003 SP2

Why is the hide from Exchange address lists not an option?

Without a lot of fiddling around, it is your only option.
Administrative group is for admin of the Exchange servers only, and you can only put servers in to an admin group at the point of installation.

The mailboxes are copies of existing user mailboxes, so the problem occurs when someone internal sends an email to a user whose mailbox we have duplicated. Using the GAL lookup, email is sent to the wrong user.

I can add a virtual exchange server to the new administrative group with no problem, if I can confirm that a new administrative group is the way to accomplish this.

So why can't you hide those mailboxes from the GAL in the usual way?
If you enable the option to hide the user from the GAL, then the GAL lookup will not work.

There are basically two ways to hide items from the GAL.

1. Enable the option on the user account.
2. Build custom address lists. That means in short replacing the default - as I put above a lot of fiddling around.

I cannot hide the mailboxes in the usual way because I need to use an archiving application against the mailboxes, and the mailbox must be visible to the GAL. This is why I need a separate GAL.

In that case you are faced with only one solution... multiple address lists.

The article on doing this was pulled last year for reasons unclear.

Strongly advise you do this in a lab first, as you have to block access to the default GAL and make a lot of other changes to the configuration of the Exchange org.

Although one does wonder if you are using the archiving solution in the way that it was intended. I have been working this site for almost three years and this is the first time I have seen a request to do this for that reason.
