After you've used a test mailbox to verify your hybrid environment is working properly, it's time to provide your %BRAND_OFFICE_365_SHORT% users with mailboxes. You can choose to either move the user's existing mailboxes to %BRAND_OFFICE_365_SHORT% or, alternatively, create a new %BRAND_OFFICE_365_SHORT% mailbox for the user.
