Well that's the question. For Exchange 2003 we had to intall the number of Cal's purchased in the license manager. How do youthat for Exchange 2007?I wouldn't like to get connection problems because insufficient licenses were installed. Must have missed something really obvious.

you cannot enter any Exchange CAL's somewhere, and there is no need, Exchange will continue to work for you regardless of how many mailboxes you create.

Thanks. Another plus for Exchange 2007.

Hi, then what is the need to get Entreprise vs standard CAL?

With Enterprise CAL you are allowed to use more server features, such as UM, advanced journaling, forefront

This is fine, but without a location to tell the server you have acquired the ECals the advanced features do not work. Has anyone figured this out? Bruce

All CAL functionality is always enabled on Exchange server. Its up to the administrator to configure them for users to use. So in the end its up to the administrators conscious

This stuff drives me absolutely bonkers. Where do you configure a mailbox/server to use the ECALs? I'm trying to get "custom managed folders" setup and can't find anywhere to setup/configure ECALs.

This was just the information I was looking for, however I have additional questions.Where can I look to identify what type of CAL I have?I'm being asked to confirm that we are compliant, is there some place that will tell me how may mailboxes/devices I am using?How can I check to ensure that I am compliant with the licenses we have ?Thank you in advance.Bob

CALS are not "installed" or "tracked" from within Exchange. It is based on the honor system. You can find out how many licenses you have by looking at your software agreement documentation.
