Explanation:
Use the New-RetentionPolicyTag cmdlet to create a retention tag.
Retention tags are used to apply retention settings to folders and individual items such as e-mail messages and
voice mail. These settings specify how long a message remains in a mailbox and the action to be taken when
the message reaches the specified retention age. When a message reaches its retention age, it’s moved to the
user’s In-Place Archive or deleted.
