We have Exchange 2010 Standard edition without any Enterprise CAL. We are wondering if we are able to enable Archive Mailbox since it displays the following message while trying to enable the feature:
A personal archive located on an on-premises Exchange Server is a premium feature and requires an Exchange Enterprise CAL for the user.
Since we don't know what the "on-premises Exchange server" means we went ahead and set up for two users with the archive mailbox. Both two uses are currently using this feature. So can you tell us if we should or shouldn't entitle this feature?
And by the way, what does "on-premises Exchange Server" mean?
