I migrated from Exchange 2003 to Exchange 2007 and since the first day that the Exchange 2007 server was installed all replies to emails in Outlook also sends the original email back to the user's Blackberry (not the reply email but the original email that I am replying to). The Exchange 2003 server is now removed from the network but this problem remains so it's not an issue with having two Exchange servers. This is happening on all Blackberries using different providers (Verizon and AT&T). The Blackberries are all setup to pop to the Exchange server. Any help on this would be appreciated. Thank you.
