Help with POP/IMAP for web based school email??

Well hello everyone, I consider myself pretty savvy and this problem arose when I tried to add my school's email to Mail.app... I took my computer into the Apple store and they were unsuccessful after about an hour of trying.

Now, I've read on Titan Apps (the section on the CSUF school portal) that you have to create a password solely for POP/IMAP access, and I did that, and I made a new Mail account with the new settings and I'm still receiving errors about the password not being right to get new mail...

I'm so stumped I've run out of ideas.. any help?
