From Microsoft Technet (http://technet.microsoft.com/en-us/library/aa998649.aspx#agent ), it mentions that Exchange 2010 provides the following journaling options: 1. Standard journaling: Standard journaling is configured on a mailbox database. It enables the Journaling agent to journal all messages sent to and from mailboxes located on a specific mailbox database. To journal all messages to and from all recipients and senders, you must configure journaling on all mailbox databases on all Mailbox servers in the organization. 2. Premium journaling: Premium journaling enables the Journaling agent to perform more granular journaling by using journal rules. Instead of journaling all mailboxes residing on a mailbox database, you can configure journal rules to match your organization's needs by journaling individual recipients or members of distribution groups. You must have an Exchange Enterprise client access license (CAL) to use premium journaling. If our customer (e.g. total 200 users) wants to use Premium journaling for some of their users e.g. 100 users, should only 100 x Exchange 2010 Enterprise CAL or 200 x Enterprise CAL be purchased? And also, if 100 Enterprise CAL is purchased but more than 100 users are using Premium journaling, are there any issues/side effects e.g. we can't turn on journaling for 101st user,...etc? Please advise. Thanks.

Thanks. Seriously, the people that can answer this question accurately are those that sell the CALs -- and I'd wager that even they are never 100% accurate. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi Problem Man, As far as I know, the 101st user can still use Premium Journaling. But as we all know, this is not illegal. Details,I would suggest you contact Microsoft directly. In the United States, call (800) 426-9400 to speak to a Microsoft representative. In Canada, call (877) 568-2495.
