Hi Folks, Scenario --------- Two Exchange servers , (front-end and Backend) I´ve installed front-end, smtp conectivity is working propperly Problem --------- 1. OWA cannot bring with /Exchange and /public folder. It´s point to M: unit. But there´s no ?M:? unit on Front-End Server because mailbox store and public store are excluded. 2. How can I enable front-end Server to answer for pop service, where pop Server should to connect on backend Server. ? Thanks Alex
