HI I have a SBS 2008 running exchange 2007 and my clients are using blackberry 9000's, the problem that they are having is that when they set up their email on their blackberry using BIS as IMAP or POP3 on blackberry.orange they recieve multiple emails when they open their outlook, read email or search their email either in the office (set up as exchange) or at home (set up as pop3). If they set it up using OWA e.g. https://mail.domain.co.uk they don't get duplicates however thay cannot send calendar invites from the blackberry. Do you have any suggestions? Thank you Mahesh

Hi Shafaquat how do I ensure that the message UIDs of email messages on the integrated account messaging server do not change. Regards Mahesh

do you have set leave a message on server check?

Hi yes we have. Also the problem seems to happen when accessing OWA aswell i have seen many forums where people have had the same problems but have not not posted a solution. Regards Mahesh
