Robert,
CALs are based on access according to: http://www.microsoft.com/exchange/2007/howtobuy/default.mspx#EKC with regards to distro groups and contacts, there is no server access from a user or device, so you do not need to purchase a cal. -troy From: Robert Peterson [mailto:robert.peter...@prin.edu] Sent: Friday, August 14, 2009 2:03 PM To: MS-Exchange Admin Issues Subject: CALs required for "Contacts"? Does anyone know and can point me to documentation on whether Exchange CALS are needed for email enabled contacts or distribution groups, since there is only forwarding and no mailboxes on the Exchanger server. My question: Active Directory allows you to setup "Contacts" that do not have security rights like "user" objects. And these contacts can be set to have a local domain e-mail address, but all mail is forwarded to an outside mail system such as their Yahoo or Gmail account. There is no mailbox storage on the Exchange server, thus the question on whether a CAL is needed? I guess this question would also concern all AD "Distribution" groups too, since it is doing the exact same thing. Thank you and have a great weekend everyone, Robert
