Groupwise addresses in Exchange

I am trying to find a good way to view and resolve GroupWise email addresses (SMTP only) through a Global Address Book in Exchange 2003 SP2.  We initially tried to have the servers communicate via connector, but the HTML in email was getting butchered, and the connector was, at times, crash-prone.  Our solution right now involves email going from the outside directly into GroupWise (@example.com) , landing in mailboxes (all users have GW mailboxes) and the Exchange users get their mail via forwarding (@migrate.example.com).  The Exchange system forwards mail to GW users by way of shared namespace (KB Article 321721).  So Groupwise users have a full address book, and don't see odd email addresses.  Exchange users see each other, but can't resolve GroupWise addresses.  We've briefly looked at LDAP, but due to the fact that this does not create entries in an OAB, not really the way we want to go.  Ideally, I'd like to create a mechanism by which we can export GW addresses and import them into AD as contacts, without having to use the Novell Groupwise Connector for Exchange.

You might guess that we are moving to Exchange, but not just yet since we have so many other projects that need to be complete first.  The people that are on Exchange now are the result of a merger, and we see no reason to move them to GW and learn a new system, only to move them right back in 12-18 months.

I'd appreciate any input, since a big part of my question is "Is this in any way possible?" Start Free Trial
