I have just helped a couple of customers who were using Outlook.com/Hotmail to set up their mail on Office 365. These customers are typical SMEs who have no time for Outlook and they find web mail sufficient for their needs.
Previously, they were using Outlook.com with their own custom domains, but Microsoft have pulled the plug rudely such that administrators can't even see who the users are in the domain or reset passwords.
My question is, as both platforms are Microsoft, why isn't there a single click option to let the users copy all their mail from Outlook.com/Hotmail to the Office 365 accounts, directly from one Microsoft server to another? Surely this will be another plus point to discourage people from going to Google Apps for Business.
For most of these users, their Microsoft accounts on Outlook.com are even exactly the same (ie spelled the same) as theirOrganization accounts on Office 365.
