If EMSX was installed in domain on an Exchange Server (3) occupying the MAILBOX role, we would see the following mailbox count in the backend of EMSX:.If EMSX was installed in domain on an Exchange Server (2) occupying the MAILBOX role, we would see the following mailbox count in the backend of EMSX:.The number of domain mailboxes in domain is 410 it is 150 in domain.There is a trust relationship between those domains, and the EMSX license is being used in both domains.

Resource mailboxes (for example, a conference room mailbox), email aliases, system mailboxes (used only for internal purposes of Microsoft Exchange Server), and disabled mailboxes are not included in the mailbox count.

The local mailbox count reflects the count of mailboxes for the Exchange server where EMSX is installed.The domain mailbox count reflects the count of all mailboxes in a specific domain to which the Exchange server (on which EMSX is installed) belongs.The Monitoring window in ESMX displays two types of mailbox counts: domain and local.
