The application can protect the number of mailboxes that does not exceed the limitation of the current key. If this number is insufficient, you can alternate protection between mailboxes. To do so, you have to move to unprotected storage the mailboxes that need no protection. By default, the application also protects all public folders of the mail server. You can remove protection from public folders if you think that scanning them would be redundant.
By default, the application protects those mailbox storages of the Microsoft Exchange server that already existed at the time when the application was installed, as well as all newly-created storages.
To configure the protection settings for mailboxes and public folders:
The Protected mailbox storages list contains the storages of mailboxes and shared folders of the protected Microsoft Exchange server.
If the application is running in a DAG of Microsoft Exchange servers, this list contains the storages of mailboxes and shared folders on all the servers within this DAG.
When viewed from a profile, the Protected mailbox storages list shows only the protected storages of those Microsoft Exchange servers on which Anti-Virus for the Mailbox role is deployed.
