        -PreferredServer.

    .PARAMETER AllowFileRestore
        The AllowFileRestore parameter specifies whether to allow a database to
        be restored from a backup.

        adding a database. Defaults to $false.

    .PARAMETER AutoDagExcludeFromMonitoring
        The AutoDagExcludedFromMonitoringparameter specifies whether to
        exclude the mailbox database from the ServerOneCopyMonitor, which
        alerts an administrator when a replicated database has only one healthy
        copy available.

    .PARAMETER BackgroundDatabaseMaintenance
        The BackgroundDatabaseMaintenance parameter specifies whether the
        Extensible Storage Engine (ESE) performs database maintenance.

    .PARAMETER CalendarLoggingQuota
        The CalendarLoggingQuota parameter specifies the maximum size of the
        log in the Recoverable Items folder of the mailbox that stores
        changes to calendar items.

    .PARAMETER CircularLoggingEnabled
        The CircularLoggingEnabled parameter specifies whether circular
        logging is enabled for the database.

    .PARAMETER DataMoveReplicationConstraint
        The DataMoveReplicationConstraint parameter specifies the throttling
        behavior for high availability mailbox moves.

    .PARAMETER DeletedItemRetention
        The DeletedItemRetention parameter specifies the length of time to keep
        deleted items in the Recoverable Items\Deletions folder in mailboxes.

    .PARAMETER DomainController
        The DomainController parameter specifies the domain controller that's
        used by this cmdlet to read data from or write data to Active
        Directory. You identify the domain controller by its fully qualified
        domain name (FQDN). For example, dc01.contoso.com.

    .PARAMETER EventHistoryRetentionPeriod
        The EventHistoryRetentionPeriod parameter specifies the length of time
        to keep event data.

    .PARAMETER IndexEnabled
        The IndexEnabled parameter specifies whether Exchange Search indexes
        the mailbox database.

    .PARAMETER IsExcludedFromProvisioning
        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.

    .PARAMETER IsExcludedFromProvisioningByOperator
        The IIsExcludedFromProvisioningByOperator parameter specifies whether
        to exclude the database from the mailbox provisioning load balancer
        that distributes new mailboxes randomly and evenly across the available
        databases.

    .PARAMETER IsExcludedFromProvisioningDueToLogicalCorruption
        The IsExcludedFromProvisioningDueToLogicalCorruption parameter
        specifies whether to exclude the database from the mailbox
        provisioning load balancer that distributes new mailboxes randomly and
        evenly across the available databases.

    .PARAMETER IsExcludedFromProvisioningReason
        The IsExcludedFromProvisioningReason parameter specifies the reason
        why you excluded the mailbox database from the mailbox provisioning
        load balancer.

    .PARAMETER IssueWarningQuota
        The IssueWarningQuota parameter specifies the warning threshold for the
        size of the mailbox.

    .PARAMETER IsSuspendedFromProvisioning
        The IsSuspendedFromProvisioning parameter specifies whether to exclude
        the database from the mailbox provisioning load balancer that

        databases.

    .PARAMETER JournalRecipient
        The JournalRecipient parameter specifies the journal recipient to use
        for per-database journaling for all mailboxes on the database.

    .PARAMETER MailboxRetention
        The MailboxRetention parameter specifies the length of time to keep
        deleted mailboxes before they are permanently deleted or purged.

    .PARAMETER MetaCacheDatabaseMaxCapacityInBytes
        The MetaCacheDatabaseMaxCapacityInBytes parameter specifies the size of
        the metacache database in bytes. To convert gigabytes to bytes,
        multiply the value by 1024^3. For terabytes to bytes, multiply by
        1024^4.

    .PARAMETER MountAtStartup
        The MountAtStartup parameter specifies whether to mount the mailbox
        database when the Microsoft Exchange Information Store service starts.

    .PARAMETER OfflineAddressBook
        The OfflineAddressBook parameter specifies the offline address book
        that's associated with the mailbox database.

    .PARAMETER ProhibitSendQuota
        The ProhibitSendQuota parameter specifies a size limit for the mailbox.
        If the mailbox reaches or exceeds this size, the mailbox can't send
        new messages, and the user receives a descriptive warning message.

    .PARAMETER ProhibitSendReceiveQuota
        The ProhibitSendReceiveQuota parameter specifies a size limit for the
        mailbox. If the mailbox reaches or exceeds this size, the mailbox can't
        send or receive new messages. Messages sent to the mailbox are returned
        to the sender with a descriptive error message. This value effectively
        determines the maximum size of the mailbox.

    .PARAMETER RecoverableItemsQuota
        The RecoverableItemsQuota parameter specifies the maximum size for the
        Recoverable Items folder of the mailbox.

    .PARAMETER RecoverableItemsWarningQuota
        The RecoverableItemsWarningQuota parameter specifies the warning
        threshold for the size of the Recoverable Items folder for the mailbox.

    .PARAMETER RetainDeletedItemsUntilBackup
        The RetainDeletedItemsUntilBackup parameter specifies whether to keep
        items in the Recoverable Items\Deletions folder of the mailbox until
        the next database backup occurs.

    .PARAMETER SkipInitialDatabaseMount
