Here is something from IWU regarding your myemail.indwes.edu email accounts. Previously, the university did not allow you to forward messages from your account for security reasons, but now you can have messages forwarded to your personal email accounts.
As a rule, instructors are now only provided with your myemail.indwes.edu email addresses by the university, and not your personal email addresses, and the university email addresses are the only approved method of communication for facilitators to use. If it is more convenient for you to email me with your personal accounts, I don’t mind that, but for emails to the entire class, I only use the myemail addresses. Your mileage may vary with other instructors.
