You can compare the number of mailboxes located on your Security Server with the number of mailboxes to which your license applies.
To view information about the number of mailboxes calculated by the application:
In the Management Console tree, perform one of the following actions:
If you want to view information about the number of mailboxes on a separate Security Server (for example, on a server in the Mailbox role or on a server within a DAG group), open the node of the Security Server for which you want to view information about the number of mailboxes.
If you want to view information about the number of mailboxes of a profile:
Open the Profiles node.
Open the node of the profile for which you want to view information about the number of mailboxes.
Select the Licensing node.
The workspace displays information about the number of mailboxes calculated by the application on your server, and information about keys that have been added.
When calculating license restrictions, the application takes into account the following types of mailboxes:
UserMailbox
LinkedMailbox
SharedMailbox
RoomMailbox
EquipmentMailbox.
The application does not take into account service mailboxes and shared folders when calculating license restrictions.
Take into account the following considerations for calculating the number of mailboxes:
On a separate Security Server (for example, on a server in the Mailbox role), the application takes into account the mailboxes located on this server.
On a server in the Hub Transport role, the number of mailboxes is always 0.
On a server in the Edge Transport role, the number of mailboxes is always 0.
On a server within a DAG group, the application takes into account the mailboxes located in active storage on this server.
In a profile, the application takes into account the mailboxes located on all servers within the profile.
To calculate the number of mailboxes, the application uses the Get-MailboxDatabase command for PowerShell, which is part of a Microsoft Exchange server. You can use this command to view the number of mailboxes on a protected Microsoft Exchange server:
