In researching how to do an alias for an external email account, I noticed that my global settings report "31 accounts used" while we only have 27 accounts. On top of that, it would appear that the only way to create an alias to an external account is to create a mailbox (thereby taking one seat) and pointing the canonical address to the outside account.
Is this accurate? Will every external forwarder really cost us one licensing seat?
I see the spam/ham training accounts are counting against our total, so system accounts count against the licenses as well?
Also, any idea about the discrepancy between # of accounts and the license count?
