You have an Exchange Server 2016 organization. The organization contains 10 mailbox
databases. You have a mailbox database named DB4 on a disk that has only 10 percent free disk space. You
need to prevent automatic mailbox distribution from selecting DB4 as a target.
Which cmdlet should you use?
A.
Set-MailBoxDatabase
B.
Set-Mai IboxServer
C.
Set-SiteMailboxProvisioningPolicy
D.
Set-DatabaseAvailabilityGroup
Set-MailboxDatabase -Identity “DB4” -IsExcludedFromProvisioning $true

The same applies for Exchange 2016
That’s right!
IsExcludedFromProvisioning
Optional
System.Boolean
The IsExcludedFromProvisioning parameter specifies whether to exclude the database from the mailbox provisioning load balancer that distributes new mailboxes randomly and evenly across the available databases. Valid values are:
$true The database is excluded from new or move mailbox operations when you don’t specify the target mailbox database.
$false The database can be used in new or move mailbox operations when you don’t specify the target mailbox database. This is the default value.
The value is automatically set to $true when you set the IsExcludedFromProvisioningDueToLogicalCorruption parameter to $true, and isn’t changed back to $false when you set the IsExcludedFromProvisioningDueToLogicalCorruption parameter back to $false. In the case of database corruption, you should set the IsExcludedFromProvisioning parameter back to $false only after you fix the corruption issue or recreate the database.
