when it says the mb does not exist, it should give you the dn that is not there. i have that problem from one voip dial tone service. talked to a user and the mailbox was 434-xxxx... we are one 4 digit mb's and my cp was getting all 7 digits from that provider. i went in and added the 7 digit dn to my mb's and it works.. with almost 2000 mb's i wish there was a better way
