I've been slowing migrating mailboxes over to Exchange 2013 from Exchange 2007 over the past week. I wanted to make sure that there wasn't going to be any new ex2013 retention policies that would instantly go into effect. How do I make sure that the default MRM isn't doing anything to my newly created mailboxes? I'd like to take some time and figure out what the retention plan should be.
I read this from a Microsoft doc:
Exchange Setup creates the retention policy Default MRM Policy. The Default MRM Policy is applied automatically to new mailboxes in Exchange Online. In Exchange Server, the policy is applied automatically if you create an archive for the new user and don’t specify a retention policy
I don't believe I've created any archives since I've been migrating.
