Special Circumstances

The migration methods presented in this chapter will work with most versions of Outlook as well as other mail clients, but you do need to keep a couple special circumstances in mind. One such occurs if you use Outlook 2007 and your current mailbox is hosted on an Microsoft Exchange Server (locally or in the cloud). Office 365 is also an Exchange mailbox, and Outlook 2007 does not allow you to have more than one Exchange mailbox in the same profile. In this case, you can export your existing mailbox to a PST (and import it into your Office 365 inbox or attach it as described later), upgrade to Outlook 2010, or use a migration service. All of these work very well to move not only your mail but also your Calendar and other information into Office 365.
