Deployed all Windows 2008 R2 DC’s, we have Exchange 2003 within the environment. If we uplift the Domain/Forest functional level to 2008, will there be any issues with exchange?

This article states we will not be able to create a new mailbox.
Is this true?
We are unable to upgrade Exchange at the moment, so I want to make sure that if the DFL/FFL is uplifted it won’t break the mail system.
Thanks
