Greetings:

Our corporation has an Exchange 5.5 organization setup. Our office is currently running Quarterdeck Mail (no jokes please). I have completed training on Exchange 2000, (hopefully I'll be certified soon) and I want to install it.

What I want to know is if I can install Exchange 2000 at my location, and have it connect and function properly with the corporate 5.5 organization? Will I be able to access the Global Address List? Can I create a connector to connect to the CorporateOrganization?

We are all indepenedent of our corporate office, and many of the sites are running 5.5.

I have Active Directory running properly, and I'm ready to go.

Any ideas and input are greatly appreciated.

Thanks.

Mike

First- work with you Corporate Exchange Admin or you wont get very far.
Second- Is your corporation deploying AD? If so you want to find out if you can leverage their AD design and if they will be moving to Exchange 2000.
Doing things on your ownwith AD and Ex2K, can be very troublesome down the road, if you corporation later has its own deployment plan's. You could lose everything you worked on, because their is currently no way to prunge and graft AD design together.
With that said...
1 Option- If you wish to co-exist with Ex5.5 you need to first install the Active Directory Connector (ADC) which will populate your Ex5.5 Information into AD. This creates users and groups in AD with references back to their 5.5 and NT accounts. Then you can install your first Exchange 2000 server, into the Ex5.5 Organization.
You do not access the GAL of Ex5.5. With the ADC populating AD with all the 5.5 accounts, you see AD represented objects, in the Address List. This list is held onGlobal Catalog servers.
2nd option- If you will truely exist seperate from your corp organization, you can use the ADC to create the mailboxes from Ex5.5 as contacts in AD, and use an x.400 or SMTP connector back to your corp office. Again you need to work with your Ex Admin people.
Hope some of that helps

Your answer is what I had assumed, but with limited time, I haven't had the chance to research it more. Thank you for your input.
