If customer specifies that they won't increase the Exchange systems then I take this to mean that we have to build the storage systems for UM messages and still provide integration to Exchange. for Unity. Does that mean that we as a vendor will have to allocate additional hardware for mailbox storage, and then integrate that with the customer's existing Exchange Infrastructre.
Is there a way to still provide integration with Exchange if the servers are not located at the core sites? I thought the Unity servers had to be located right along side of each Exchange server for UM.
