Exchange 2003, separating GAL based on OU

Good day all!

Here's what I'm looking to-do.  Not sure if it's possible or not.  

We recently merged with another firm and have two decent size offices (NY, LA).  I'd like to set it up so that when you go to send an email in Outlook, you can change the "Show addresses from the" and have it show the office, but you could select the drop down and get the full GAL or the alterante office.  I'd like to configure it so by default, the office get's just that office's contacts.

Each office is in it's own OU and runs their own copy of Exchange 2003 and the desktops are configured with Outlook 2003 and Outlook 2000.  

Make sense?  I hope so.

create a group for each office,
and then configure the GAL permission to deny each office the access of the GAL of the other office by right click on it and select the security tab

I'd like them to be able to see the other offices, just not their default view.

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

I figured this out.  

In Active Directory,  we coded each user in active directory by filling in the "Office"-- LA or NYC
In Exchange System Manager, Go to receipents|All Address lists.  
Right click new address list.
Name the lists and use the Filter function to sort out which office is which.

Now when the users go into Outloook,  they can change just bring up which ever office by selecting-- "Show names from the".

If they want to make one of the offices their default address book, in Outlook 2003:
- Tools|Addressbook
- in the address book- Tools|Options
- show this address list first: select the office.

I put this to be points refunded since I fingured it out.  Not sure what else to do?

Nope. You had not :)
When you need something to be PAQ'd/deleted and points refunded, you need to ask in CS/General:

This one will be handled in cleanup but for the future, follow the usual way. Thanks
