I'm trying to determine which two of the following three accounts is counting against my Exchange CAL's for a client:
This client has 44 mailboxes shown in the Exchange 2010 Organizational Health Summary, yet when I count mailboxes, I come up with 46. I discount DiscoverySearchMailbox as not using a license, so that leaves 45 in question. I can account for 42 actual user mailboxes plus the three mentioned above which leads me to conclude that two of those three are using CAL's. I've searched here and Google with various text but don't see an answer to this, any thoughts?
