You need to add a default policy tag to a retention policy

You have an Exchange organization. All servers in the organization have Exchange Server 2010 SP1 installed.

You create a retention policy and apply the policy to all of the mailboxes in the organization.

You need to add a default policy tag to a retention policy. The tag must move all email messages automatically to a Personal Archive six months after the messages are received.

What should you do first?

A.
Run the Set-Mailbox -identity “user1” -RetentionHoldEnabled $true command.

B.
Create a Retention Policy Tag that uses the Personal Folders tag type.

C.
Run the Set-RetentionPolicyTag -identity “never delete” -type Personal command.

D.
Modify the management role groups.

E.
Create a Retention Policy Tag that uses the all other folders tag type.

F.
Modify the User Role Assignment Policy.

G.
Run the Set-RetentionPolicyTag -identity “never delete” -type All command.

H.
Run the Set-RetentionPolicyTag | Set-RetentionPolicyTag -RetentionEnabled $false command.

I.
Run the Set-Mailbox -identity “user1” -SingleItemRecoveryEnabled $true command.

Explanation:
You can’t create Retention Policy Tags (RPTs – for default folders such as Inbox and Deleted Items) with the Move to Archive action.

The Move To Archive action is only supported for Default Policy Tag (Type = ‘All’) or Personal Tags.

The former applies to the entire mailbox. The latter can be used by Outlook 2010/OWA users to tag individual folders or items.

And you need to create an archive mailbox for the user.

So the correct command is the following:

New-RetentionPolicyTag “InboxMovetoArchive30days” -Type “All/Personal -Comment “Inbox move to archive in 30 days” -RetentionEnabled $true -AgeLimitForRetention 30 -RetentionAction MovetoArchive

New-RetentionPolicy “ManagedFoldersRetentionPolicy” -RetentionPolicyTagLinks ” InboxMovetoArchive30days “
