Office 365 IMAP mailbox migration error: MigrationRecipientNotFoundException

microsoft-office-365

I have tried to do this migration twice now and I get the same error.

Error: MigrationRecipientNotFoundException: A recipient wasn‎'t found for "orders@example.com" on the target. Create a recipient of the appropriate type for this migration on the target and try again.

I know that on my target (Exchange online server) I have an account named orders@mydomain.com and have an account named orders@example.com at the source. I have two domains, the default example.net and the example.com. Any help would be greatly appreciated.

Issue had to do with the fact that even though the user was created in office 365, it didn't have a corresponding exchange mailbox. By creating a mailbox for this Office 365 user the migration succeeded.
