We had been using LN Domino for about 9 years with very few problems. My company moved us to exchange two months ago so we can get Microsoft CRM, essentially for nothing. Worse move we ever made. Compared to LN Outlook is very very slow, frequently needs the exchange server rebooted and after CRM was loaded it runs even slower. The contacts DB takes so many mouse clicks that I can't use it when talking on the phone. Staff discontent is rapidly rising, some staff are now using gmail on their own initiative. If this is what Microsoft call enterprise SW then they are dreaming.
