Microsoft Exchange Licensing
The Microsoft Exchange system is licensed in multiple ways both from the server and client perspectives. The following information is provided to ensure the licensing situation for Exchange is understood.
Server
ACNS has procured the necessary licensing for the servers running the Microsoft Exchange services. Each server's operating system and the Exchange server software itself has an associated license which allows us to run the servers.
Client
Client Software
The Microsoft Outlook and Microsoft Entourage clients must be licensed by the end-user in order to make the connection between these software packages and Exchange. If your department participates in the Campus Agreement with Microsoft, you may already be licensed for the Microsoft Office suite including the Outlook program. Outlook and Entourage may also be purchased on a per-user basis through the ACNS Software Cellar via the Microsoft Select Licensing Agreement.
Client Access Licenses
Two Client Access Licenses (CALs) are required for each user who connects to a Microsoft Exchange server mailbox, regardless of the method by which the access is made (Outlook/Entourage/Evolution, IMAP(Thunderbird,Eudora), mobile phone sync(BlackBerry, Windows Mobile Activesync), or Outlook Web Access).
The two required CALs are: Exchange Standard CAL 2007 and Windows Server 2003 User CAL.
ACNS periodically analyzes who on our campus is utilizing the Exchange system, and we ensure that we have enough Exchange 2007 Standard CALs to cover everyone using the system (via a combination of counting the number of Exchange users covered under the Campus Agreement "Core CAL" and by ACNS purchasing enough Exchange 2007 Standard CALs via the Microsoft Select Licensing Agreement to cover those not under the Campus Agreement).
The Windows Server 2003 User CAL is the responsibility of each department to purchase. Those with the Campus Agreement "Core CAL" are automatically covered for this CAL and ACNS has determined that enough Windows Server 2003 User CALs have been purchased through the Microsoft Select Licensing Agreement to cover those not under Campus Agreement.
However, please keep in mind that your department must ensure that you are covered either under Campus Agreement or the Select Agreement for the Windows Server 2003 User CAL.
Importantly, you must also understand that if ACNS upgrades the Exchange server infrastructure to a new version of the Windows Server operating system, you will be required to ensure that your Windows Server 2003 User CAL is likewise upgraded to the new server version (by one of the following ways: renew your Campus Agreement, you may have purchased Software Assurance for your Windows Server 2003 User CAL under the Select Licensing Agreement, or you newly purchase enough Windows Server XXXX (the next version) User CALs to cover your userbase).
Forefront Security for Exchange Server 2007
Forefront Security is a product that runs on the Exchange 2007 server infrastructure and is licensed on a per-user basis outside of the Campus Agreement licensing method. ACNS covers the cost of the Forefront Security product, and therefore end-users and departments need not be concerned with the licensing of this piece of Exchange. Forefront is an anti-virus/anti-spam filtering system much like the Trend ScanMail software in use with other Exchange systems on campus.
