Can anyone describe what takes place in this situation. Installing a new Unity Server VM only (only one) we are using a exsisting Exchange Server 2000. Going through the setup of Unity the message store section. What is the purpose of this to have full admin rights to Exchange server....my understanding is that the message store will be installed to the Unity server not Exchange server
Unity uses Exchange 5.5, 200(x) or Domino for it's message store - it does not use it's own proprietary message store and then synch it to the mailboxes in question - the messages originate there.
You need to point Unity at an Exchange server that will act as our "partner" server - we need to be able to log into all mailboxes for message retrieval and message notification functions and be able to create mailboxes and directory (in this case AD) accounts.
This is true for VM only as well as UM. If you plan to use an existing Exchange installation as your VM platform that's fine but you'll want to create users that are hidden in the address book (4.0(3) has this on the profile page for subscribers in the SA) such that they don't show up in the email address books of the desktop clients... you don't want VM only users getting normal emails that they can't retrieve - it'll just clutter up their inbox.
Are you getting this error “Installer User Interface Mode Not Supported. The installer cannot run in this UI mode. To specify the interface mode, use the -i command-line option, followed by the UI mode identifier. The value UI mode identifiers...
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.
