Can a Move-Mailbox operation run moving data only, without the attributes. We are doing a phase migration (this will take about a week) and don't want to stamp the mailboxes until all the data is migrated over. The migrating accounts are currently contacts in our E2K7 environment.

Can a Move-Mailbox operation run moving data only, without the attributes. No, it is not possible. When a move mailbox happens, the attributes from AD are taken as well.If you don't want to stamp the mailboxes, you can exclude the user from it in the exchange server 2007. A better suggestion will be to put the users in a particular store and exclude them.- Nagesh
