RUS and Mailbox Management policies when migrating to Exchange 2007
Posted on 2009-04-12
We are currently running Exchange 2003 SP2. We have four domains in our Active Directory - Florida, California, NY and Texas. Exchange is organized so that each domain is also a routing group/ Admin group in Exch. NY is the hub site which mails go to the Internet from/to.
FL will be migrated to Exchange 2007 first. The problem is, we have recipient update policies and mailbox management policies set for the entire 2003 organisation (although each domain has a seperate RUS server).
We have installed the FL CAS and Hub Transport server so far. From what I can see, the existing RUS policy has been copied over as an E-mail Address policy, but the 'Applied' status is False. The Mailbox Management policy from 2003 does not seem to have been copied over - although I'm not sure if this is because we don't have a 2007 Mailbox server as yet in the org.
Does anyone know what will happen to the Mailbox Management policy (delete Inbox emails after 70 days etc) when we co-exist? Will the 2003 policy be applied to any mailboxes on 2007? Is there the chance that a 2007 policy will affect mailboxes on 2003?
Secondly, is it possible to set Mailbox Management policies for only a subset of users (e.g. one domain) in the EMC?
And, thirdly, what will happen to the RUS/E-mail Address policy?
