You have an Exchange Server 2013 organization.
Your company has a Service Level Agreement (SLA) stating that you must be able to reconnect disconnected
mailboxes to user accounts for up to 365 days. After 365 days, disconnected mailboxes must be deleted
permanently.
You need to recommend a solution to meet the SLA.
What should you include in the recommendation?
A.
Create a retention policy and apply the policy to all mailboxes.
B.
Configure the deleted mailbox retention setting for all databases.
C.
Configure the deleted item retention setting for all databases.
D.
Implement a database availability group (DAG) that contains a lagged copy.
Explanation:
Recoverable Items Folder Exchange 2013
The Recoverable Items folder replaces the feature known as the dumpster in Exchange Server 2007. The
Recoverable Items folder is used by the following Exchange features:
Deleted item retention
Single item recovery
In-Place Hold
Litigation hold
Mailbox audit logging
Calendar logging
Disconnected Mailboxes
Each Microsoft Exchange mailbox consists of an Active Directory user account and the mailbox data stored inthe Exchange mailbox database. All configuration data for a mailbox is stored in the Exchange attributes of the
Active Directory user object. The mailbox database contains the mail data that’s in the mailbox associated with
the user account. The following figure shows the components of a mailbox.
A disconnected mailbox is a mailbox object in the mailbox database that isn’t associated with an Active
Directory user account. There are two types of disconnected mailboxes:
Disabled mailboxes
When a mailbox is disabled or deleted in the Exchange Administration Center (EAC) or using the DisableMailbox or Remove-Mailbox cmdlet in the Exchange Management Shell, Exchange retains the deleted mailbox
in the mailbox database, and switches the mailbox to a disabled state. This is why mailboxes that are either
disabled or deleted are referred to as disabled mailboxes. The difference is that when you disable a mailbox,
the Exchange attributes are removed from the corresponding Active Directory user account, but the user
account is retained. When you delete a mailbox, both the Exchange attributes and the Active Directory user
account are deleted.
Disabled and deleted mailboxes are retained in the mailbox database until the deleted mailbox retention period
expires, which is 30 days by default. After the retention period expires, the mailbox is permanently deleted (also
called purged). If a mailbox is deleted using the Remove-Mailbox cmdlet, it’s also retained for the duration of
the retention period.
Important:
If a mailbox is deleted using the Remove-Mailbox cmdlet and either the Permanent or StoreMailboxIdentity
parameter, it will be immediately deleted from the mailbox database.
To identify the disabled mailboxes in your organization, run the following command in the Shell.
Get-MailboxDatabase | Get-MailboxStatistics | Where { $_.DisconnectReason -eq “Disabled” } | ft
DisplayName,Database,DisconnectDate
Soft-deleted mailboxes
When a mailbox is moved to a different mailbox database, Exchange doesn’t fully delete the mailbox from the
source mailbox database when the move is complete. Instead, the mailbox in the source mailbox database is
switched to a soft-deleted state. Like disabled mailboxes, soft-deleted mailboxes are retained in the source
database either until the deleted mailbox retention period expires or until the Remove-StoreMailbox cmdlet is
used to purge the mailbox.
Run the following command to identify soft-deleted mailboxes in your organization.
Get-MailboxDatabase | Get-MailboxStatistics | Where { $_.DisconnectReason -eq “SoftDeleted” } | ft
DisplayName,Database,DisconnectDate

B
Disabled and deleted mailboxes are retained in the mailbox database until the deleted mailbox retention period
expires, which is 30 days by default.
This example configures a deleted item retention period of 365 days for the mailbox database MDB2.
Set-MailboxDatabase -Identity MDB2 -DeletedItemRetention 365
Content can be retained using a variety of built-in functions such as:
Journaling: With journaling, the organization can have exact copies of content captured and retained in a
separate database (a “journaling database”) to ensure the content has not been tampered with and is available
for legal search and review at a future time Retention Policy: Content within an Exchange environment can be
set to be retained (or purged) based on policies set on the Exchange databases, so either configured through
the Exchange Admin console or through a PowerShell command like Set-MailboxDatabase -Identity MDB4 –
eletedItemRetention 365 to hold content from being deleted off the Exchange server
Personal Archives: Each user in Exchange can have their primary mailbox and an Archive mailbox where the
archive mailbox can have content drag/dropped to the archive box for long term storage, similar to what users
have historically used Personal Store (PST) files in the past. Unlike a PST file that is almost completely
unmanaged by the organization (yet is still considered legal evidence), the Personal Archive in Exchange is part
of the Exchange environment with content that can be searched, set for long term retention, and put on legal
hold.
