CodeTwo Office 365 Migration will let you easily migrate users’ mailboxes from on-premises Exchange Server to Office 365. The program enables direct migrations from Exchange 2003, 2007, 2010, 2013 or 2016. It also supports migrations between Office 365 tenants. What's more, you can use it to migrate email folders from servers supporting IMAP, like IBM Notes (formerly Lotus Notes), Zarafa, etc., to Microsoft's Cloud. The target mailbox can use any Office 365 plan available in the Microsoft Online Services offer that includes Exchange Online.

The table below will help you verify if your migration scenario is supported and what types of items are migrated in it by CodeTwo Office 365 Migration. In case of any questions, contact us. We are available 24 hours a day, 5 days a week.
