I have a customer who wants UM using his exchange 5.5 cluster. I know that Unity is not supported with a 5.5 cluster (but does with 2000) but I can't find any basic information explaining why.
What I'm really looking for is a work around until the 5.5 is upgraded to 2000. For example would it be possible to deploy an additional Exchange server into the same org/site but isn't part of the cluster. Unity could then use this as it's partner server.
Any info or ideas would be great (I know it's a bit of an Exchange question rather than Unity).
The wording in one document is "Cisco Unity for Exchange 5.5 does not support mailboxes on Exchange 5.5 clusters.". If it's possible to install another 5.5 server into the existing "site" (but not into the cluster) and partner Unity to that box, I would assume that technically the mailboxes that I want Unity to retrieve and deliver messages to are actually homed on the cluster. In this instance I would not place any user mailboxes on the partner Exchange, just use it as a transit to the rest of the "site". If this is OK as a configuration it kind of contradicts the statement above.
Also, what's the very basic reason why Unity can't talk to a 5.5 Exchange Cluster, but can a 2000 Cluster. I can't see how Unity is really aware that the server is clustered (but I do know v. little about Exchange and clustering). Do you have a good reference to the reasoning why it can't be done.
I want to be sure that we can provide UM to the customer even though they have a 5.5 cluster by providing another Exchange server connected to their site and cluster, otherwise we will have to force them down the VM route instead. Hence the need for a bit of confirmation.
It is not supported for Unity to service mailboxes which are homed on an Exchange 5.5 clustered server. Clusters are a bit different from non-clustered servers. There really hasn't been the business case for us to invest time in testing, qualifying and supported Exchange 5.5 clusters. If you have a large opportunity you should work with the Account Manager and they can try to push for support.
I also have a customer who is looking to use the Cisco Unity solution and has a Microsoft Exchange 5.5 Cluster on Windows 2000 Advanced server. The Domain is still NT4. Is there any workaround to allow this customer to use the Cisco Unity solution. Would it be possible to configure them for Voice Mail only, if the Unified messaging solution won't work?
Yeah you would need to do VM only if they can't move to an E2K/E2K3 cluster. The mailboxes would need to be homed on a non-clustered server.
If it is a large opportunity I suggest working with the account team and trying sell a business care for support. We only have a limited number of engineering/QA resources so we want to try to get the most bang for our buck when to do product testing/support. Exchange 5.5 clusters are pretty rare so we haven't seen the business case to work with them...

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
