My company is switching to Exchange 2010 from Groupwise. I'm trying to find out some specifics about the user CALs, and well a direct answer seems hard to come by.
First off is a Enterprise user CAL required on all mailboxes we may want to put a legal hold on at some point? Not all of our employees need all of the features of the Enterprise CALs. But at some point if we need to put a legal hold on someone's e-mail down the road am I going to have to assign them a enterprise cal before I can issue a legal hold on their mailbox?
Also, I understand that a Enterprise CAL is needed for multi-mailbox search. Is the Enterprise CAL just needed for the person doing the multi-mailbox search, and the other user's mailboxes can be standard CALs, or does the mailbox require a Enterprise CAL to be searchable?
Thanks in advance.
