DRAG DROP
You have an Exchange Server organization named adatum.com. The organization contains servers
that have Exchange Server 2010 and Exchange Server 2013 installed.
The company executives require that all email messages remain stored for three years.
You create two retention tags named Ret1 and Ret2. Ret1 moves the email messages to an Archive
mailbox after one year. Ret2 permanently deletes the email messages after three years.
You need to meet the company executives’ requirements. The solution must ensure that all email
messages that are older than two years are removed as quickly as possible.
Which three actions should you perform in sequence? (To answer, move the appropriate three
actions from the list of actions to the answer area and arrange them in the correct order.)
Answer: 
Add the tags to a policy, assign the policy to the users, run start-managedfolderassistant to apply the policy to the users straight away.
The third step is one that nobody seems to talk about in any of the guides, but I figured this out when I followed it through in a lab and policies were not applying.
