Help Importing Exchange to iOS5

[CMK0110]

I have my work email, on an exchange server, set up flawlessly on my MBP through iMail, iCal and Address Book. I tried to import it to my iPhone during the iOS5 upgrade but it didn't go through. I don't see the account in iTunes when I try to force it to sync and I'm unable to get my iPhone to add the account when I go through the settings on the the phone using the same settings for the account that are being used for that same account in iMail. Has anyone else experienced this before? Is there a workaround. I have a BlackBerry, but I'm looking to dump it in favor of my iPhone 24/7/365 if I can get my account set up. Any help would be great!
