  • Correcting my response because I misread the question.

    For a cutover migration, you have the option of either doing a cutover migration back, which is pretty much the same process as you did when you cut over to Office 365, just the other way, or setting up a hybrid configuration with on-premises Exchange and running the two together until you've moved all the mailboxes back.

  • Ed is correct, however if you have not already migrated to O365 you might want to test a single mailbox migrating and rolling back as;



    Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 --> 2007 --> 2010 --> 2013 with Lucid8's DigiScope

  • How do you migrate a single mailbox with a cutover migration?

  • Third-party cloud tools like MigrationWiz and Cloudiway can do that.

    You can also do the same thing with Outlook and a PST.
