I haven’t been able to access my IU email account. Whenever I click on it through one.iu it says that I have an invalid email and they are unable to process my request at this time. Any advice?
Are you an IU student already? If so, I would stop by UITS on the first floor of Wells in the west wing. If not, maybe email the admissions office and have them connect you to the right person. That would take a few days at least though
Thank you, I fixed the issue 
Glad you got it fixed
