Just spent 30 minutes on the phone with Microsoft support to figure out how one migrates (a crappy term to begin with. It suggests moving from one place to another. In reality it’s more of a 1-way sync) email accounts from an Exchange server to the mailboxes that come with Office 365 Small Business.
Why hide it like this? Who knows…? Microsoft Moves in a Mysterious Way…
Update: It appears Microsoft has changed their URL-scheme. You still first go to the Outlook Web App, but from there you can go to https://outlook.office365.com/ecp/ to access the Exchange Control Panel for Office 365.--
