My question is if it possible to deploy Exchange server 2007 in an AD site
that have RODC only? I know that Exchange cannot work with RODC. I understand
that is not much sense in such configuration. But, in principal, can Exchange
be in an AD site with RODC only and use a writable DC from other sites for

Asked another way, can Exchange work in an AD site where there are no
DC or DCs?
It may work, but why would you want to use that sort of configuration?
You'll have to use out-of-site DCs and GCs and that's kinda dumb.
"No version of Microsoft Exchange uses read-only domain controllers
(RODCs) or read-only global catalog servers (ROGCs). However,
Microsoft Exchange works in environments that include RODCs or ROGCs,
as long as there are writeable domain controllers available. Exchange
2007 effectively ignores RODCs and ROGCs. Exchange 2003 also ignores
RODCs and ROGCs in default conditions where Exchange components
automatically detect available domain controllers. No changes were
made to Exchange 2003 to make it read-only directory server-aware.
Therefore, trying to force Exchange 2003 services and management tools
to use RODCs may result in unpredictable behavior. "
