Many thanks for the great explanation...

<div class="content wysiwyg-content">
I currently run SBS 2008 at home (not for business, but because I like the features).<br />
<br />
I am thinking of migrating my email to a cloud based service - specifically Office 365. My question is this though.<br />
<br />
Does Office 365 Home Premium offer the same email provision as Office 365 Hosted Exchange Only?<br />
<br />
I have multiple domain names - can I add those to a Home Premium account? <br />
How much Exchange space does each Home Premium mailbox get?<br />
Can I access Exchange using my iPhone still?<br />
Do I get calendars and can I share them with other Home Premium members?<br />
<br />
I'm not worried about AD integration at all.<br />
<br />
Thanks

Office 365: Home Premium vs Exchange Online

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.

Microsoft 365

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
