We are installing Unity 4.0(2) with Exchange 2k for voicemail only usage. Unity & Exchange will be on the same box and it will house roughly 50-100 voicemail users for now. We are planning on attaching the server to our AD network but need some information on caveats/recommendations for our situation. Our domain is using Domino/Notes for email without any exchange tie-ins. Our concern is bringing Exchange 2k into our environment (without a connector to notes) and what the implications are in doing so. We are concerned on what exactly Exchange (including forestprep and domainprep) will do to our domain, schema and current email users. Also, if we do bring exchange on-line with our domain, how will users be allocated/created for Notes email usage and Exchange 2k voicemail usage.
Any suggestions/comments would be greatly appreciated.
