2.5 License
A very important step is to enter the license file for ESET Mail Security for Microsoft Exchange Server. Without it, email
protection on the Microsoft Exchange Server will not work properly. If you do not add the license file during
installation, you can do so later in the advanced settings, under
Miscellaneous > Licenses
.
ESET Mail Security 4 for Microsoft Exchange Server (EMSX) compares the number of mailboxes for the active directory
to your license count. Each Exchange server's active directory is checked to determine the total mailbox count. There is
no way to determine which mailboxes are protected and which ones are excluded from protection. Resource
mailboxes (i.e. a conference room mailbox) will be tallied in the mailbox count. Email aliases are not tallied in the
mailbox count. In a clustered environment, nodes with clustered mailbox role are not tallied in the mailbox count.
To determine how many Exchange enabled mailboxes you have, open
Active Directory users and computers
on the
server. Right-click on the domain and click
Find...
. Then from the
Find
drop-down menu select
Custom search
and
click the
Advanced
tab. Paste in the following Lightweight Directory Access Protocol (LDAP) query and click
Find Now
:
(&(objectClass=user)(objectCategory=person)(mailNickname=*)(|(homeMDB=*)
(msExchHomeServerName=*))(!(name=SystemMailbox{*))(!(name=CAS_{*))(msExchUserAccountControl=0)
(!userAccountControl:1.2.840.113556.1.4.803:=2))
