How do I find/obtain an enterprise account Acivation Passord?

I have recently switched from Vodaphone to EE and after having unlocked my Blackberry 9800 and inserted the EE sim, I find that I cannot reset up my e-mail accounts in the usual manner (inserting an e-mail address and then the account's password).
This time I am asked for a "Enterprise Account" Activation Password, which I do not have. When I Google this subject, it appears that I need to obtain this from my Administrator, which is me I suppose. What do I need to do to obtain this password?
The phone and texting part of the BB is working OK.

Your phone has an IT policy.
