I had a couple accounts already on my o365 instance (therefore had a Mailbox) and they migrated great with MigrationWIZ. However with accounts that I created with DirSync, I get this error:
Your migration failed checking destination credentials. The SMTP address has no mailbox associated with it. Error: ErrorNonExistentMailbox Detail: SmtpAddress
How do I get the account to have a mailbox associated with it so the migration will work?
Thanks!
