I migrated from Exchange 2k3 to 2010 and things are working, however I cannot connect any new outlook profiles to the new server regardless of outlook verson (2010, 2007, or 2003). All of the mailboxes reside on the new server and the clients that were already configured are fine after the migration (the switched over successfully) but if I try to connect any other outlook client (new or existing) I am getting an error "Outlook cannot logon...." and then "Exchange server unavailable. I can at least resolve the name in the profile if I use the old exchange server name, but then get the same error. I am new to EE, so please let me know if I can improve my posting until I get the hang of this. Thanks
FYI, Exchange 2010 SP1, 2008 R2 Standard, majoriy of Outlook clients are 2010 and a few 2003 (the 2003 have the RPC encryption setting turned on). 3rd pary cert which is working fine for activesync and webmail.
