Exchange 2010 License CALs

Hi,

We purchased Windows Server 2008 R2 with 25 user CALs and Exchange 2010 Standard with user 25 CALs . Now we have more than 30 mailboxes and 25 domain users.

Are we required to get more CALs?

How does user CALs work on Exchange server? For example, in warehouse, there are 5 people working but there are only 3 PCs with outlook installed (accessing to only one mailbox) and only one user account is being used. Does this count 1CALs or 5CALs?

Microsoft licenses per USER (HUMAN BEING) or per DEVICE.  You CAN mix licenses.  If the people in the warehouse ONLY access e-mail through a warehouse computer, then the warehouse computer can have a single device CAL and it will cover all users.  Your office workers who get email on their phones, tablets, laptops, desktops, and through web mail should then have USER CALs.
