I've built a new network which includes several windows server 2008 VMs and exchange 2010.
On my test bench everything seems to work okay, 2 test clients can join the domain and can send and receive emails.
The thing is, I haven't (as yet) installed any device / user CALs.
I'm implementing this network tomorrow on a test basis in an environment of 20 users. Will it work or do I need to get device / user CALs??
