Please help

Ok I have an htc touch pro. And my work email is very important. I had it fowarded to my gmail then to my phone. This does not work well as it shows as a fw and if i reply it goes to my gmail not to the person that sent the email. I use microsoft exchange and I did get the info to set it up with my phone the right way. The problem is any email I get in my inbox comes in perfectly. However I have folders for all the people I get emails from and none of those emails will show up. Can not figure out the issue. Any help would be a huge help
