Sounds like you installed the CCM license instead of the CME license. For example, for a 12 mailbox license, you will see license files similar to cue-vm-license_12mbx_cme_2.3.x.pkg and cue-vm-license_12mbx_ccm_2.3.x.pkg. Changing to the CME license will require a reinstallation. See the following link for confirmation.
