I am getting ready to upgrade our exchange server. We currently are running exchange 2003 with about 70 mailboxes. Clients are all using office 2010 (outlook 2010) and that will not be getting upgraded. We also have 10 blackberry devices running off Blackberry enterprise server.
I'm looking some advice on which would be better fit exchange 2010 or 2013? Does either offer better services for mobile devices?
Thanks for advice
