I am having trouble to find this info online and we hope to get this right so we get acquire the right number of CALs.
We have a Windows Server 2008 network, with Exchange 2010.
I understand that Windows server and Exchange CALs are not concurrent. Put it simple, if we have 120 staffs each have his/her own mailbox we will then need 120 Windows server and Exchange CALs, am I correct?
What confuses me is that if we have situation where a user has TWO email accounts (two mailboxes), and we add mailbox2 to his outlook so he only have one login account, does this count as one CAL or two?
Also, if we have people who left the company, but we want to keep their emails, do we have to retain the CALs for them?
Thanks in advance for anyone who shed some light.
