With exchange 2003, outlook 2003 was also on the CD
but when you buy an exchange 2007 user license (which is about 100 us$), you DON'T get the neccessary (outlook) client that you need too.
Nope, the client is sold separately. (another 100 us$)
Microsoft thinks that everyone uses the microsoft 2007 office suite
well, the professional suite (which "fortunately" has outlook in it) costs about 450 us$
So to get exchange 2007 working, you pay AT LEAST about 200 us$ per user!
(compare that to groupwise, which costs AT MOST 130 us$ per user)
These prices are all the maximum commercial prices....
btw. there are some good working commercial migration programs to migrate from groupwise to exchange, but they cost another 100 us$ per user
and that is EVERY user in groupwise.
- External entities also will become full licensend users
- Resources also will become full licensed users
hope this helps....
in the end groupwise is cheaper
