I can connect to my 2010 mailboxes with activesync, but, when i try to connect to 2003 accounts through the 2010 server, i get an error on my device saying "unable to find server" and then this shows up in the http logs "LdapC1_LdapL16_Error:TiSyncStateLocked_Mbx:2003server".
how does exchange 2010 proxy the connection? does it use rpc over http on the backend?
would it be sensitive to the 2003 servers ssl certificate, or will it just communicate as a hostname?
any help would be appriciated...
