This weekend we've moved over to a new windows domain and migrated our Exchange 2003 server to a new Exchange 2012 server. Now suddenly only our Blackberry users are receiving random intercompany emails, mails that are definitely not addressed to them! Our old exchange 2003 server is disconnected from the network, we do not have any internal BES server (hosted via KPN.blackberry.com), I've added firewall rules to block out all Blackberry servers in a desperate attempt to stop this, only the blackberries are affected, Iphone/Android users are OK.
The affected BB users only have these incorrectly addressed emails on their mobile device, it's not received in Outlook.
Please help! I'm clueless how this can happen, looks like the Blackberry server's routing is completely random!
