If you are an Exchange 2010 user and want to migrate your all mailboxes into Office 365, in that case, I would recommend you try the Shoviv Exchange Migration tool. This tool also migrates Office 365/Live Exchange public folder and archive mailboxes into another Office 365/Live Exchange public folder and Archive Mailboxes. It has also a free demo version that helps the users to know about its features and working process. The demo version will also help you to migrate the first 50 items per folder.
