What error message did you get?

Does she have it set up in Outlook or some other PC email client on a PC or Mac? If so, you can use the same settings on the BB.

To set up in BIS, you will need the user name, password and incoming server ans if it is a POP or IMAP account. Sometime you will also need the proper ports as well. You should be able to get that from the school IT department.

I really doubt that anyone here would know that unless they used the same setup.
