Hi, after installing outlook 2007 in windows vista with exchange account I
did'nt found exchange shared calendar and public folder too, even if exchange
mail works correctly. In calendar menu I can't find "Find shared calendar"
link. I tried to forward the calendar from outllook 2003, but outlook 2007
blocked the e-mail beacause "dangerous". Can u help me? thanks
