In a near future we will leave the Netware ship to join the Microsoft one. And for what i've read here .. it's for the better on the BES side.... Just wondering if there is some major "advise your boss before going there" issue on the exchange side of the world? I mean with Groupwise we runned flawlessly till we changed for the 4.1 version... Since then we have issue with Read/unread/delete message synch (especially when you delete lots of email in one shot), or issue with the address book synch. I guessed that these issue are not "known issue submitted to engineering" like we often see in the bes for groupwise. Can someone confirm my impression on that?
