Hello,<br />
<br />
I have an Exchange 2007 server on premise which hosts multiple mailboxes on multiple primary email domains. <br />
<br />
I want to migrate all of the mailboxes on only one of the domains, mydomain.com, away from my on premise and to Office365.<br />
I want to leave the remaining mailboxes, who do not have email addresses with @mydomain.com on premise.<br />
I also want to be able to migrate any dist. groups or public folders related to @mydomain.com<br />
<br />
What is the right migration method for this scenario? A cutover? (of sorts)<br />
<br />
Thanks<br />
<br />

Single Domain migration to Office365 - leaving remaining domains on-premise

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.
