Hi there, Just want to have your input if any one came across or had dealt with the similar scenario as follows: Is it possible that if we install an SBS 2008 for mainly share exchange server/ share point service / active sync and blackberry services with 3 different companies? It is like a exchange hosted solution on a smaller scale to keep the cost down for three small businesses. Any Licensing issue? Isolated global address list? any other advise?regardsHaider
