My father wants his corporate email on his BB. HE doesnt want to pay the extra $15 for it so I mentioned the BES Express but Im not sure how it works or will it work for him. I dont know if the company actually has to have the Express server for him to use it? Also, Ive been reading around that Verizon is planning to make BESX users pay the extra amount? Any help would be great.

Yes, the company needs to install BES Express and hook it into the Exchange Server. So, unless he has access to the servers, this may not work for him.

As for the corporate mail, if they have Outlook Web Access he should be able to get his mail through BIS -- might be a bit of a delay, but not huge.
