You are the messaging engineer for your company. Your company has an Exchange Server 2007 messaging system.
You need to recommend a solution that allows for the recovery of deleted mailboxes and deleted e-mail.
Your solution must meet the following requirements:
Deleted e-mail should not be recoverable after two days.
Deleted mailboxes should not be recoverable after two days.
All existing mailboxes databases must be configured to meet these requirements.
Any new mailbox databases created in the future must automatically be configured to meet these requirements.
What should you recommend?
A.
Using the Exchange Management Console, configure the Maintenance schedule to run daily. Configure the Deleted item retention setting to two days for each recipient.
B.
Using the Exchange Management Console, configure the settings of each mailbox database. Configure the Deletion settings to retain deleted items and deleted mailboxes for two days.
C.
Using the Exchange Management Shell, retrieve a list of all mailbox databases. Set the deleted mailbox and deleted e-mail retention time properties to two days. Schedule this command to run once a day.
D.
Create a managed content setting for the Entire Mailbox managed default folder. Configure the content setting to retain all messages for two days. Create a new managed folder mailbox policy that includes the Entire Mailbox folder. Assign the new mailbox policy to all mailboxes on all mailbox databases. Schedule the managed folder assistant on all mailbox servers to run once a day.

Use Get-MailboxDatabase to retrieve one or more mailbox database objects from a storage group, server, or organization. Without parameters, returns all databases in the organization.

Use Set-MailboxDatabase to set database properties. Use DeletedItemRetention and MailboxRetention to specify length of time to keep deleted items and mailboxes. Enter values as a time span: dd.hh:mm:ss, where d = days, h = hours, m = minutes, and s = seconds. The maximum time is 24,855 days. (By default, deleted items and mailboxes are retained for 14 and 30 days, respectively.) These parameters apply, respectively, to all mailboxes in the database and to all mailboxes without their own item retention attribute set. RetainDeletedItemsUntilBackup determines whether to retain delete items until after the next backup; possible values: $true or $false.
