Cannot Migrate from Outlook (Zoho Migration Wizard needed?)

I am trying to migrate my company email users from Outlook to Zoho, but it has not been possible. I already verified my domain, and changed the MX Records in my DNS Settings in Godaddy, and I already created a migration using the Outlook IMAp settings, but when I try to add the user accounts, It rejects the username and password that I have for each user in Outlook. Do I need the Migration Wizard to do this? Can you send the file? How do I overcome this issue?
