CAL Licensing for Exchange 2003 mailbox servers mixed with 2007 CAS and HT

In an environment where an end user goes through an Exchange 2007 CAS and/or Exchange 2007 HT server but has their mailbox hosted on an Exchange 2003 Mailbox server, is that user required to have an Exchange 2007 CAL?  I would assume so but thought I would see if anyone knows for sure.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes, you will need a 2007 Standard CAL for your end users in that scenario.
