Well, the short answer is theres no clean way to fully integrate a Unity server with a GroupWise server and client.
The longer, more sticky answer starts with a clarification on what you mean by integrate.
If youre looking at using Unity for voice mail only (i.e. not a unified messaging system) you have some options. Certainly Novell has some good tools to integrate their NDS with NTs directory so you could certainly have that setup and have NT accounts automatically created on the Unity server which could then be associated with Unity subscribers in Exchange. This makes AA access from the desktop nice and smooth when the site is using Novell as their primary network since they dont have to authenticate (i.e. their security token matches from their Novell login). Head out to Novells web site, they have bunches of info on their NDS for NT stuff and their support pages have PDF files with good details on the ins and outs of how this works.
Doing a true unified messaging model in this type of environment would be impossible, however. While Novell does have a synchronizer for Exchange 5.5, it works in much the same way as the Lotus connector does. It essentially sets up proxy email users on either side and shuttles messages across. It does not maintain the read/deleted state of messages across stores which means your notification and MWI triggers would be out of whack. For instance if you got a new voice mail in Unity, we stuff it in your Exchange account. The synchronizer would then copy that message over to your GroupWise account where you see it at the desktop. Since there is no VMO equivalent for GroupWise youd see this as an email with an attached WAV. When you opened it and listened to it, Unity will not know this and we will leave your MWI on until you call in over the phone or access your Exchange inbox via Outlook. Not ideal. If you setup the connector to MOVE the message instead of copying it, even worse. Unity now has no record of your message, no MWI goes out, no notifications and if you call in over the phone well say you have no new messages but youll see a new voice mail in your GroupWise inbox.
Further the message class of the messages themselves is many times not preserved when theyre moved across the connector (true for Lotus and GroupWise) so faxes, for instance, would not come across as faxes, they would be emails with attached TIF files. Finally, youd have to delete messages over the phone if you didnt have a separate client to access the Exchange store if you didnt do that your inbox on Exchange would eventually fill up.
Probably about as close as you could get would be to have the GroupWise client for email and the Outlook client for voice mail/faxes on every desktop. Probably a little cluttered and more expensive than folks would be looking for, but workable perhaps.
So far as I know theres no way to get any message client to read two stores at once. You can get it to poll a POP3 account and pull messages over to your primary store but theres no way to have a single client look at two primary stores (i.e. leave messages there and let you manipulate their state from the client). If someone knows of a snappy way around this, Im all ears! I cant imagine how itd get around handing messages from different stores with potentially different directories, however thatd be very tricky stuff. When you hit reply on a message itd have to be very smart about which address book it presented to you as possible destinations.
Anyway probably more information than you were looking for, but hopefully I answered your question in there somewhere.

Well I suppose my thoughts on this depend on what youre hoping to do with it.
It seems like a fine solution for allowing folks to use the Outlook desktop client to get at their mail store on a Groupwise server or vice versa. Novell has always done a good job interoperating with other systems (i.e. their integration into the NT model is fantastic).
If, however, youre hoping to simply plug this MAPI drop in onto a Unity server and have us provide unified messaging services on a Groupwise back end, this is a very long way from everything wed need.
My first concern would be, of course, the MAPI plug in itself is clearly written as a single client access scenario and even with that their FAQ mentions performance issues several times. Being able to fire up 72 simultaneous sessions is a whole different ball of wax. Microsoft spent a lot of time with us early on getting the MAPI stuff worked out (and they just got the last of our major issues ironed on in SP4!). I would fully expect Novell would have to step up to some serious development commitments to take it to the level necessary. Lots and lots of work
My next observation is that we need a lot more than just a link to get to the mail store. The directory is a big part of what we need Wed have to write a connector for Novell just as we had to for Exchange (and are for AD and Domino). This is a pretty major development and testing effort all by itself. I suppose you could weasle on some of that if Novell has a really tight AD integration, but it still woldn't get you seamless user creation/editing of the mail users/properties... the kind of "god" level access we need to send messages as other users, monitor their message store for changes and the like.
If, instead, youre just looking for a way to have Groupwise clients be able to connect to an Exchange message store and get voice mail services, I suppose this plug in gets you part of the way there. Theyd at least be able to get their voice mail as an attached WAV file to an email, but not much more than that. A VMO plug in for a Groupwise client is not in the works so far as I know.
We use Groupwise as our main message store for e-mail, and NDS for permissions. It has worked well for several thousand users over 7 years. We upgraded to 5.5 and were interested in using the redundant message store with all the administration features for managing our Voice Mail and VOIP (Cisco callmanager) accounts.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...

No. You will only need the SRST licenses on the primary router. Because this feature...
